====== Ubuntu - Backups - Backup using rsnapshot ======

rsnapshot is a remote filesystem snapshot utility, based on rsync.

  * rsnapshot hardlinks files if they already exists and the backups do not take much more space than the actual filesystem you are backing up.

----

===== Configure =====

An example config file (/root/scripts/rsnapshot-home.conf) to backup a remote file-server.

<file bash /root/scripts/rsnapshot-home.conf>
config_version  1.2
snapshot_root   /media/Backup/
cmd_cp  /bin/cp
cmd_rm  /bin/rm
cmd_rsync       /usr/bin/rsync
cmd_ssh /usr/bin/ssh
cmd_logger      /usr/bin/logger
cmd_du  /usr/bin/du
interval        daily   7
interval        weekly  4
interval        monthly 3
verbose 2
loglevel        4
logfile /var/log/rsnapshot-home.log
exclude_file    /root/scripts/rsnapshot-home.exclude
rsync_long_args --delete        --numeric-ids   --delete-excluded
lockfile        /var/run/rsnapshot.pid
backup  username@example.com:/export/files/      files/
</file>

<WRAP info>
**NOTE:**  The config file is tab delimited so you will get errors if you use space instead!

===== Manual daily backup =====

<WRAP info>
**NOTE:**  A passwordless SSH connection should be configured from the backup server to the file server if you plan to run this as a automated job using crontab.
</WRAP>


<code bash>
sudo rsnapshot -c /root/scripts/rsnapshot-home.conf daily
</code>

<WRAP info>
**NOTE:**  This will produce a folder structure like this with the backups

<code>
/media/Backup/daily.0/files
/media/Backup/daily.1/files
/media/Backup/daily.2/files
/media/Backup/daily.3/files
...
</code>

Where daily.0 is the newest backup.

  * The backup files are store in the same form as on the file server so they can be browsed using a regular file browser.

===== Reports =====

A report can be configured to be sent after every backup with the perl script **rsnapreport.pl**.
