How to Automate Backups in Virtuozzo?

The virtual environments (VE’s) within Virtuozzo can be integrated with the Windows Scheduler to have automated backups performed.

By creating a simple batch file and integrating it with our Command Line Interface (CLI), the process can run at regular intervals on the server. Both full and incremental backups can be performed through the Windows Scheduler. The command used to backup a VE is called vzbackup. Examples of how to perform each type of backup is listed below.

While running this command, vzbackup does the following:

* It connects via SSH to the Source Node where the identified VE you wish to back up resides;
* It compresses the private area of the selected VE and its registry settings to a .zip formatted file;
* It connects via SSH to the Backup Node
* It transfers the compressed file to a special backup folder on the Backup Node


For example, to back up a single VE (101) hosted on a Hardware Node, the command below would back it up on that server.

vzbackup 101


To have the scripted backup create a backup on Host Node (10.10.40.100) and send it to the Backup Node (10.10.40.200), the following command would be used:

vzbackup 101 -A 10.10.40.200 –U Administrator –P passwd200


Where

-U is the Administrator login to the backup node. This option can be omitted – in this case vzagent0 password should be used with the –P option.
-P is the password of the Administrator ID to the specified server
-A is the IP address of the Backup Node to receive the backup

Note: In case you have the Service VE in the NAT mode you have to use the Node IP with –A option. In case you have Service VE without the NAT mode, you will use the Service VE IP with –A option.

In the example below, this backup script allows all the VE’s to be backed up at once:

Full backup:

@echo off

for /F "skip=3 usebackq tokens=*" %%i in (`cmd /c "vzlist -ao veid"`) do (cmd /c "vzbackup "%%i && echo VE ID %%i has been backed up!)


Incremental backup for Virtuozzo 3.5.1:

@echo off

for /F "skip=3 usebackq tokens=*" %%i in (`cmd /c "vzlist -ao veid"`) do (cmd /c "vzbackup -I "%%i && echo VE ID %%i has been backed up!)


Incremental backup for Virtuozzo 4.0:

@echo off

for /F "skip=3 usebackq tokens=*" %%i in (`cmd /c "vzlist -ao veid"`) do (cmd /c "vzbackup" %%i -I && echo VE ID %%i has been backed up!)



If you would like to keep a logging of backup process you can use the following script:

@echo Off >> logtime.log Time /tfor /F "skip=3 usebackq tokens=*" %%i in (`cmd /c "vzlist -ao veid"`) do (cmd /c logtime "Starting Full Local Backup of VPS %%i") && (cmd /c "vzbackup "%%i) && (cmd /c logtime "Full Local Backup Completed for VPS ID %%i")


Then you can see logtime.log file and check if backup was done successfully or not.

The following script creates report's files including number and type of backups for each container on the node:

for /F "skip=3 usebackq tokens=*" %%i in (`cmd /c "vzlist -ao veid"`) do echo ---------------- >> c:\Backup\BackupLogCT%%i.txt &time /T >> c:\Backup\BackupLogCT%%i.txt &date /T >> c:\Backup\BackupLogCT%%i.txt &vzbackup list %%i >> c:\Backup\BackupLogCT%%i.txt
