NAME

rsnapshot - remote filesystem snapshot utility


SYNOPSIS

rsnapshot [-vtxqVD] [-c cfgfile] [command] [args]


DESCRIPTION

rsnapshot is a filesystem snapshot utility. It can take incremental snapshots of local and remote filesystems for any number of machines.

Local filesystem snapshots are handled with rsync(1). Secure remote connections are handled with rsync over ssh(1), while anonymous rsync connections simply use an rsync server. Both remote and local transfers depend on rsync.

rsnapshot saves much more disk space than you might imagine. The amount of space required is roughly the size of one full backup, plus a copy of each additional file that is changed. rsnapshot makes extensive use of hard links, so if the file doesn't change, the next snapshot is simply a hard link to the exact same file.

rsnapshot will typically be invoked as root by a cron job, or series of cron jobs. It is possible, however, to run as any arbitrary user with an alternate configuration file.

All important options are specified in a configuration file, which is located by default at /etc/rsnapshot.conf. An alternate file can be specified on the command line. There are also additional options which can be passed on the command line.

The command line options are as follows:

-v verbose, show shell commands being executed

-t test, show shell commands that would be executed

-c path to alternate config file

-x one filesystem, don't cross partitions within each backup point

-q quiet, suppress non-fatal warnings

-V same as -v, but with more detail

-D a firehose of diagnostic information


CONFIGURATION

/etc/rsnapshot.conf is the default configuration file. All parameters in this file must be separated by tabs. /etc/rsnapshot.conf.default can be used as a reference.

It is recommended that you copy /etc/rsnapshot.conf.default to /etc/rsnapshot.conf, and then modify /etc/rsnapshot.conf to suit your needs.

Long lines may be split over several lines. ``Continuation'' lines must begin with a space or a tab character. Continuation lines will have all leading and trailing whitespace stripped off, and then be appended with an intervening tab character to the previous line when the configuation file is parsed.

Here is a list of allowed parameters:

config_version Config file version (required). Default is 1.2

snapshot_root Local filesystem path to save all snapshots

include_conf Include another file in the configuration at this point. =over 4

This is recursive, but you may need to be careful about paths when specifying which file to include. We check to see if the file you have specified is readable, and will yell an error if it isn't. We recommend using a full path. As a special case, include_conf's value may be enclosed in `backticks` in which case it will be executed and whatever it spits to STDOUT will be included in the configuration. Note that shell meta-characters may be interpreted.

no_create_root If set to 1, rsnapshot won't create snapshot_root directory

cmd_rsync Full path to rsync (required)

cmd_ssh Full path to ssh (optional)

cmd_cp Full path to cp (optional, but must be GNU version)

If you are using Linux, you should uncomment cmd_cp. If you are using a platform which does not have GNU cp, you should leave cmd_cp commented out.

With GNU cp, rsnapshot can take care of both normal files and special files (such as FIFOs, sockets, and block/character devices) in one pass.

If cmd_cp is disabled, rsnapshot will use its own built-in function, native_cp_al() to backup up regular files and directories. This will then be followed up by a separate call to rsync, to move the special files over (assuming there are any).

cmd_rm Full path to rm (optional)

cmd_logger Full path to logger (optional, for syslog support)

cmd_du Full path to du (optional, for disk usage reports)

cmd_rsnapshot_diff Full path to rsnapshot-diff (optional)

cmd_preexec

Full path (plus any arguments) to preexec script (optional). This script will run immediately before each backup operation (but not any rotations).

cmd_postexec

Full path (plus any arguments) to postexec script (optional). This script will run immediately after each backup operation (but not any rotations).

linux_lvm_cmd_lvcreate

linux_lvm_cmd_lvremove

linux_lvm_cmd_mount

linux_lvm_cmd_umount

Paths to lvcreate, lvremove, mount and umount commands, for use with Linux LVMs. The lvcreate, lvremove, mount and umount commands are required for managing snapshots of LVM volumes and are otherwise optional.

retain [name] [number]

``name'' refers to the name of this backup level (e.g., hourly, daily, so also called the 'interval'). ``number'' is the number of snapshots for this type of interval that will be retained. The value of ``name'' will be the command passed to rsnapshot to perform this type of backup.

A deprecated alias for 'retain' is 'interval'.

Example: retain hourly 6

[root@localhost]# rsnapshot hourly

For this example, every time this is run, the following will happen:

<snapshot_root>/hourly.5/ will be deleted, if it exists.

<snapshot_root>/hourly.{1,2,3,4} will all be rotated +1, if they exist.

<snapshot_root>/hourly.0/ will be copied to <snapshot_root>/hourly.1/ using hard links.

Each backup point (explained below) will then be rsynced to the corresponding directories in <snapshot_root>/hourly.0/

Backup levels must be specified in the config file in order, from most frequent to least frequent. The first entry is the one which will be synced with the backup points. The subsequent backup levels (e.g., daily, weekly, etc) simply rotate, with each higher backup level pulling from the one below it for its .0 directory.

Example:

retain hourly 6

retain daily 7

retain weekly 4

daily.0/ will be copied from hourly.5/, and weekly.0/ will be copied from daily.6/

hourly.0/ will be rsynced directly from the filesystem.

link_dest 1

If your version of rsync supports --link-dest (2.5.7 or newer), you can enable this to let rsync handle some things that GNU cp or the built-in subroutines would otherwise do. Enabling this makes rsnapshot take a slightly more complicated code branch, but it's the best way to support special files on non-Linux systems.

sync_first 1

sync_first changes the behaviour of rsnapshot. When this is enabled, all calls to rsnapshot with various backup levels simply rotate files. All backups are handled by calling rsnapshot with the ``sync'' argument. The synced files are stored in a ``.sync'' directory under the snapshot_root.

This allows better recovery in the event that rsnapshot is interrupted in the middle of a sync operation, since the sync step and rotation steps are separated. This also means that you can easily run ``rsnapshot sync'' on the command line without fear of forcing all the other directories to rotate up. This benefit comes at the cost of one more snapshot worth of disk space. The default is 0 (off).

verbose 2

The amount of information to print out when the program is run. Allowed values are 1 through 5. The default is 2.

    1        Quiet            Show fatal errors only
    2        Default          Show warnings and errors
    3        Verbose          Show equivalent shell commands being executed
    4        Extra Verbose    Same as verbose, but with more detail
    5        Debug            All kinds of information

loglevel 3

This number means the same thing as verbose above, but it determines how much data is written to the logfile, if one is being written.

The only thing missing from this at the higher levels is the direct output from rsync. We hope to add support for this in a future release.

logfile /var/log/rsnapshot

Full filesystem path to the rsnapshot log file. If this is defined, a log file will be written, with the amount of data being controlled by loglevel. If this is commented out, no log file will be written.

include [file-name-pattern]

This gets passed directly to rsync using the --include directive. This parameter can be specified as many times as needed, with one pattern defined per line. See the rsync(1) man page for the syntax.

exclude [file-name-pattern]

This gets passed directly to rsync using the --exclude directive. This parameter can be specified as many times as needed, with one pattern defined per line. See the rsync(1) man page for the syntax.

include_file /path/to/include/file

This gets passed directly to rsync using the --include-from directive. See the rsync(1) man page for the syntax.

exclude_file /path/to/exclude/file

This gets passed directly to rsync using the --exclude-from directive. See the rsync(1) man page for the syntax.

rsync_short_args -a

List of short arguments to pass to rsync. If not specified, ``-a'' is the default. Please note that these must be all next to each other. For example, ``-az'' is valid, while ``-a -z'' is not.

``-a'' is rsync's ``archive mode'' which tells it to copy as much of the filesystem metadata as it can for each file. This specifically does *not* include information about hard links, as that would greatly increase rsync's memory usage and slow it down. If you need to preserve hard links in your backups, then add ``H'' to this.

rsync_long_args --delete --numeric-ids --relative --delete-excluded

List of long arguments to pass to rsync. The default values are --delete --numeric-ids --relative --delete-excluded This means that the directory structure in each backup point destination will match that in the backup point source.

Quotes are permitted in rsync_long_args, eg --rsync-path=``sudo /usr/bin/rsync''. You may use either single (') or double (``) quotes, but nested quotes (including mixed nested quotes) are not permitted. Similar quoting is also allowed in per-backup-point rsync_long_args.

ssh_args -p 22

Arguments to be passed to ssh. If not specified, the default is none.

du_args -csh

Arguments to be passed to du. If not specified, the default is -csh. GNU du supports -csh, BSD du supports -csk, Solaris du doesn't support -c at all. The GNU version is recommended, since it offers the most features.

lockfile /var/run/rsnapshot.pid

stop_on_stale_lockfile 0

Lockfile to use when rsnapshot is run. This prevents a second invocation from clobbering the first one. If not specified, no lock file is used. Make sure to use a directory that is not world writeable for security reasons. Use of a lock file is strongly recommended.

If a lockfile exists when rsnapshot starts, it will try to read the file and stop with an error if it can't. If it *can* read the file, it sees if a process exists with the PID noted in the file. If it does, rsnapshot stops with an error message. If there is no process with that PID, then we assume that the lockfile is stale and ignore it *unless* stop_on_stale_lockfile is set to 1 in which case we stop.

stop_on_stale_lockfile defaults to 0.

one_fs 1

Prevents rsync from crossing filesystem partitions. Setting this to a value of 1 enables this feature. 0 turns it off. This parameter is optional. The default is 0 (off).

use_lazy_deletes 1

Changes default behavior of rsnapshot and does not initially remove the oldest snapshot. Instead it moves that directory to _delete.[processid] and continues as normal. Once the backup has been completed, the lockfile will be removed before rsnapshot starts deleting the directory.

Enabling this means that snapshots get taken sooner (since the delete doesn't come first), and any other rsnapshot processes are allowed to start while the final delete is happening. This benefit comes at the cost of using more disk space. The default is 0 (off).

The details of how this works have changed in rsnapshot version 1.3.1. Originally you could only ever have one .delete directory per backup level. Now you can have many, so if your next (eg) hourly backup kicks off while the previous one is still doing a lazy delete you may temporarily have extra _delete directories hanging around.

linux_lvm_snapshotsize 2G

LVM snapshot(s) size (lvcreate --size option).

linux_lvm_snapshotname rsnapshot

Name to be used when creating the LVM logical volume snapshot(s) (lvcreate --name option).

linux_lvm_vgpath /dev

Path to the LVM Volume Groups.

linux_lvm_mountpath /mnt/lvm-snapshot

Mount point to use to temporarily mount the snapshot(s).

backup /etc/ localhost/

backup root@example.com:/etc/ example.com/

backup rsync://example.com/path2/ example.com/

backup /var/ localhost/ one_fs=1

backup lvm://vg0/home/path2/ lvm-vg0/

backup_script /usr/local/bin/backup_pgsql.sh pgsql_backup/

Examples:

backup /etc/ localhost/

Backs up /etc/ to <snapshot_root>/<retain>.0/localhost/etc/ using rsync on the local filesystem

backup /usr/local/ localhost/

Backs up /usr/local/ to <snapshot_root>/<retain>.0/localhost/usr/local/ using rsync on the local filesystem

backup root@example.com:/etc/ example.com/

Backs up root@example.com:/etc/ to <snapshot_root>/<retain>.0/example.com/etc/ using rsync over ssh

backup root@example.com:/usr/local/ example.com/

Backs up root@example.com:/usr/local/ to <snapshot_root>/<retain>.0/example.com/usr/local/ using rsync over ssh

backup rsync://example.com/pub/ example.com/pub/

Backs up rsync://example.com/pub/ to <snapshot_root>/<retain>.0/example.com/pub/ using an anonymous rsync server. Please note that unlike backing up local paths and using rsync over ssh, rsync servers have ``modules'', which are top level directories that are exported. Therefore, the module should also be specified in the destination path, as shown in the example above (the pub/ directory at the end).

backup /var/ localhost/ one_fs=1

This is the same as the other examples, but notice the fourth column. This is how you specify per-backup-point options to over-ride global settings. This extra parameter can take several options, separated by commas.

It is most useful when specifying per-backup rsync excludes thus:

backup root@somehost:/ somehost +rsync_long_args=--exclude=/var/spool/

Note the + sign. That tells rsnapshot to add to the list of arguments to pass to rsync instead of replacing the list.

backup lvm://vg0/home/path2/ lvm-vg0/

Backs up the LVM logical volume called home, of volume group vg0, to <snapshot_root>/<interval>.0/lvm-vg0/. Will create, mount, backup, unmount and remove an LVM snapshot for each lvm:// entry.

backup_script /usr/local/bin/backup_database.sh db_backup/

In this example, we specify a script or program to run. This script should simply create files and/or directories in its current working directory. rsnapshot will then take that output and move it into the directory specified in the third column.

Please note that whatever is in the destination directory will be completely deleted and recreated. For this reason, rsnapshot prevents you from specifying a destination directory for a backup_script that will clobber other backups.

So in this example, say the backup_database.sh script simply runs a command like:

#!/bin/sh

mysqldump -uusername mydatabase > mydatabase.sql

chmod u=r,go= mydatabase.sql # r-------- (0400)

rsnapshot will take the generated ``mydatabase.sql'' file and move it into the <snapshot_root>/<retain>.0/db_backup/ directory. On subsequent runs, rsnapshot checks the differences between the files created against the previous files. If the backup script generates the same output on the next run, the files will be hard linked against the previous ones, and no additional disk space will be taken up.

Remember that tabs must separate all elements, and that there must be a trailing slash on the end of every directory.

A hash mark (#) on the beginning of a line is treated as a comment.

Putting it all together (an example file):

USAGE

rsnapshot can be used by any user, but for system-wide backups you will probably want to run it as root.

Since backups usually get neglected if human intervention is required, the preferred way is to run it from cron.

When you are first setting up your backups, you will probably also want to run it from the command line once or twice to get a feel for what it's doing.

Here is an example crontab entry, assuming that backup levels hourly, daily, weekly and monthly have been defined in /etc/rsnapshot.conf

0 */4 * * * /usr/local/bin/rsnapshot hourly

50 23 * * * /usr/local/bin/rsnapshot daily

40 23 * * 6 /usr/local/bin/rsnapshot weekly

30 23 1 * * /usr/local/bin/rsnapshot monthly

This example will do the following:

6 hourly backups a day (once every 4 hours, at 0,4,8,12,16,20)

1 daily backup every day, at 11:50PM

1 weekly backup every week, at 11:40PM, on Saturdays (6th day of week)

1 monthly backup every month, at 11:30PM on the 1st day of the month

It is usually a good idea to schedule the larger backup levels to run a bit before the lower ones. For example, in the crontab above, notice that ``daily'' runs 10 minutes before ``hourly''. The main reason for this is that the daily rotate will pull out the oldest hourly and make that the youngest daily (which means that the next hourly rotate will not need to delete the oldest hourly), which is more efficient. A secondary reason is that it is harder to predict how long the lowest backup level will take, since it needs to actually do an rsync of the source as well as the rotate that all backups do.

If rsnapshot takes longer than 10 minutes to do the ``daily'' rotate (which usually includes deleting the oldest daily snapshot), then you should increase the time between the backup levels. Otherwise (assuming you have set the lockfile parameter, as is recommended) your hourly snapshot will fail sometimes because the daily still has the lock.

Remember that these are just the times that the program runs. To set the number of backups stored, set the retain numbers in /etc/rsnapshot.conf

To check the disk space used by rsnapshot, you can call it with the ``du'' argument.

For example:

rsnapshot du

This will show you exactly how much disk space is taken up in the snapshot root. This feature requires the UNIX du command to be installed on your system, for it to support the ``-csh'' command line arguments, and to be in your path. You can also override your path settings and the flags passed to du using the cmd_du and du_args parameters.

It is also possible to pass a relative file path as a second argument, to get a report on a particular file or subdirectory.

rsnapshot du localhost/home/

The GNU version of ``du'' is preferred. The BSD version works well also, but does not support the -h flag (use -k instead, to see the totals in kilobytes). Other versions of ``du'', such as Solaris, may not work at all.

To check the differences between two directories, call rsnapshot with the ``diff'' argument, followed by two backup levels or directory paths.

For example:

rsnapshot diff daily.0 daily.1

rsnapshot diff daily.0/localhost/etc daily.1/localhost/etc

rsnapshot diff /.snapshots/daily.0 /.snapshots/daily.1

This will call the rsnapshot-diff program, which will scan both directories looking for differences (based on hard links).

rsnapshot sync

When sync_first is enabled, rsnapshot must first be called with the sync argument, followed by the other usual cron entries. The sync should happen as the lowest, most frequent backup level, and right before. For example:

0 */4 * * * /usr/local/bin/rsnapshot sync && /usr/local/bin/rsnapshot hourly

50 23 * * * /usr/local/bin/rsnapshot daily

40 23 1,8,15,22 * * /usr/local/bin/rsnapshot weekly

30 23 1 * * /usr/local/bin/rsnapshot monthly

The sync operation simply runs rsync and all backup scripts. In this scenario, all calls simply rotate directories, even the lowest backup level.

rsnapshot sync [dest]

When sync_first is enabled, all sync behaviour happens during an additional sync step (see above). When using the sync argument, it is also possible to specify a backup point destination as an optional parameter. If this is done, only backup points sharing that destination path will be synced.

For example, let's say that example.com is a destination path shared by one or more of your backup points.

rsnapshot sync example.com

This command will only sync the files that normally get backed up into example.com. It will NOT get any other backup points with slightly different values (like example.com/etc/, for example). In order to sync example.com/etc, you would need to run rsnapshot again, using example.com/etc as the optional parameter.


EXIT VALUES

0 All operations completed successfully

1 A fatal error occurred

2 Some warnings occurred, but the backup still finished


FILES

/etc/rsnapshot.conf


SEE ALSO

rsync(1), ssh(1), logger(1), sshd(1), ssh-keygen(1), perl(1), cp(1), du(1), crontab(1)


DIAGNOSTICS

Use the -t flag to see what commands would have been executed. This will show you the commands rsnapshot would try to run. There are a few minor differences (for example, not showing an attempt to remove the lockfile because it wasn't really created in the test), but should give you a very good idea what will happen.

Using the -v, -V, and -D flags will print increasingly more information to STDOUT.

Make sure you don't have spaces in the config file that you think are actually tabs.

Much other weird behavior can probably be attributed to plain old file system permissions and ssh authentication issues.


BUGS

Please report bugs (and other comments) to the rsnapshot-discuss mailing list:

http://lists.sourceforge.net/lists/listinfo/rsnapshot-discuss


NOTES

Make sure your /etc/rsnapshot.conf file has all elements separated by tabs. See /etc/rsnapshot.conf.default for a working example file.

Make sure you put a trailing slash on the end of all directory references. If you don't, you may have extra directories created in your snapshots. For more information on how the trailing slash is handled, see the rsync(1) manpage.

Make sure to make the snapshot directory chmod 700 and owned by root (assuming backups are made by the root user). If the snapshot directory is readable by other users, they will be able to modify the snapshots containing their files, thus destroying the integrity of the snapshots.

If you would like regular users to be able to restore their own backups, there are a number of ways this can be accomplished. One such scenario would be:

Set snapshot_root to /.private/.snapshots in /etc/rsnapshot.conf

Set the file permissions on these directories as follows:

drwx------ /.private

drwxr-xr-x /.private/.snapshots

Export the /.private/.snapshots directory over read-only NFS, a read-only Samba share, etc.

See the rsnapshot HOWTO for more information on making backups accessible to non-privileged users.

For ssh to work unattended through cron, you will probably want to use public key logins. Create an ssh key with no passphrase for root, and install the public key on each machine you want to backup. If you are backing up system files from remote machines, this probably means unattended root logins. Another possibility is to create a second user on the machine just for backups. Give the user a different name such as ``rsnapshot'', but keep the UID and GID set to 0, to give root privileges. However, make logins more restrictive, either through ssh configuration, or using an alternate shell.

BE CAREFUL! If the private key is obtained by an attacker, they will have free run of all the systems involved. If you are unclear on how to do this, see ssh(1), sshd(1), and ssh-keygen(1).

Backup scripts are run as the same user that rsnapshot is running as. Typically this is root. Make sure that all of your backup scripts are only writable by root, and that they don't call any other programs that aren't owned by root. If you fail to do this, anyone who can write to the backup script or any program it calls can fully take over the machine. Of course, this is not a situation unique to rsnapshot.

By default, rsync transfers are done using the --numeric-ids option. This means that user names and group names are ignored during transfers, but the UID/GID information is kept intact. The assumption is that the backups will be restored in the same environment they came from. Without this option, restoring backups for multiple heterogeneous servers would be unmanageable. If you are archiving snapshots with GNU tar, you may want to use the --numeric-owner parameter. Also, keep a copy of the archived system's /etc/passwd and /etc/group files handy for the UID/GID to name mapping.

If you remove backup points in the config file, the previously archived files under those points will permanently stay in the snapshots directory unless you remove the files yourself. If you want to conserve disk space, you will need to go into the <snapshot_root> directory and manually remove the files from the smallest backup level's ``.0'' directory.

For example, if you were previously backing up /home/ with a destination of localhost/, and hourly is your smallest backup level, you would need to do the following to reclaim that disk space:

rm -rf <snapshot_root>/hourly.0/localhost/home/

Please note that the other snapshots previously made of /home/ will still be using that disk space, but since the files are flushed out of hourly.0/, they will no longer be copied to the subsequent directories, and will thus be removed in due time as the rotations happen.
