Puppet module and scripts to create lvm backup and wrapper to do lvm backup of kvm lists.

All scripts are really simple, but were quite usefull for me so i guess could be source of inspiration for others :-D

Puppet module

Includes puppet module to copy selected script and schedule a cron job.

Example :

backup {'sys_backup':
  hour         => 21,
  minute       => 30,
  script       => 'lvm_backup.sh',
  script_args  => 'sys',
}->
  backup {'kvm_backup':
  hour   => 23,
  minute => 00,
  script => 'kvm_backup.sh',
}

Scripts

You can find two of them

• files/lvm_backup.sh
• files/kvm_backup.sh

lvm_backup.sh

This script is used to create backup of LVs. It will get list of LVs identified with prefix. For example if you run ./lvm_backup.sh sys_ from LVs: sys_home sys_test bigtest

only first two will be backed up.

At the beggining of sctipt you can declare basic variables - like volume group name, disk to mount as an backup disk and so on.

kvm_backup.sh

Is only wrapper for lvm_backup.sh, it gets list of virtual machines from libvirt and runs lvm_backup.sh with prefixes to backup them.
