Backup VM using rsnapshot

hi

We have ESX 3.5 Update2.
Howto backup running VM using rsnapshot?

Hi,

1. Setup Key Based Authentication and then

copy the pub id named as authorization keys on remote host.

Code:

[root@local-host]# ssh-keygen



[root@local-host]# ssh -i ~/.ssh/id_rsa.pub remote-host

2. Verify the password less login between servers.

Code:

[root@local-host]# ssh remote-host

Last login: Sun Mar 15 16:45:40 2009 from local-host



[root@remote-host]#

3. Configure rsnapshot and specify Remote Host Backup Directories

Define your remote-host destination backup directories in /etc/rsnapshot.conf as shown below. In this example,

* root@remote-host:/etc – Source directory on the remote-host that should be backed-up. i.e remote backup destination directory.

* remote-host-backup/ – destination directory where the backup of the remote-host will be stored. Please note that this directory will be created under local-host /.snapshots/{internal.n}/ directory as shown in the last step.

Code:

# vi /etc/rsnapshot.conf



backup  root@remote-host:/etc/  remote-host-backup/  exclude=mtab,exclude=core

4.) Test rsnapshot Configuration

Perform configuration test to make sure rsnapshot is setup properly and ready to perform Linux rsync backup.

May be this would be helpful.

Enjoy ;)

Thx a lot, I'll try.

BTW has anyone already tried to backup a running VM using rsnapshot?

Yes but I'm running KVM, not VMWare ESX. I used to run VMWare Server 1.x and installed rsnapshot on a host to backup directories/files on the guests. The password-less logins described by dev_dks were part of my solution also.
