= Vzdump =
Vzdump is an utility to make consistent snapshots of running OpenVZ VEs. It basically creates a tar archive of the VE private area, which also includes the VE configuration files.
There are several ways to provide consistency:
- Stop the VE during backup (very long downtime)
- Use rsync and suspend/resume (minimal downtime)
- Use LVM2 (no downtime)
Vzdump stores the backup on the disk in a single file. This file should go to a tape backup for archiving.
== Download ==
Download vzdump rpm or deb packages from http://download.openvz.org/contrib/utils/vzdump/
For rpm based systems:
<pre>wget http://download.openvz.org/contrib/utils/vzdump/vzdump_0.3-1_all.deb</pre>
For Debian based systems:
<pre>wget http://download.openvz.org/contrib/utils/vzdump/vzdump-0.3-1.noarch.rpm</pre>
== Installation ==
For rpm based systems:
<pre>rpm -i vzdump-0.3-1.noarch.rpm</pre>
For Debian based systems:
<pre>dpkg -i vzdump_0.3-1_all.deb</pre>
== Synopsis ==
<pre>vzdump OPTIONS [--all â <VEID>]
--compress compress dump file (gzip)
--dumpdir DIR store resulting files in DIR
--xdelta create a differential backup using xdelta
--mailto EMAIL send notification mail to EMAIL
--stop stop/start VPS if running

</pre>
= Examples =
== Backup ==
Simply dump VE 777 - no snapshot, just archive the VE private area and configuration files to the default dump directory (usually /vz/dump/).
<pre>vzdump 777</pre>
Use rsync and suspend/resume to create a snapshot (minimal downtime).
<pre>vzdump --suspend 777</pre>
Backup all VEs and send notification mails to root.
<pre>vzdump --suspend --all --mailto root</pre>
Use LVM2 to create snapshots (no downtime).
<pre>vzdump --dumpdir /space/backup --snapshot 777</pre>
== Restore ==
Restore above backup to VE 600
<pre>vzdump --restore /space/backup/vzdump-777.tar 600</pre>
