Not sure if your script need be run regularly. Do you need the backup between 5am ~ 8am? If it is, to put it in cronjob will be good idea, with that you needn't change your code if the time is changed in the future. For example, the backup time is changed.

Code:
0 0-4,9-23 * * 0 /PATH/your_script

NAME
vgcfgbackup - backup volume group descriptor area SYNOPSIS
vgcfgbackup [-d|--debug] [-f|--file filename] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose] [VolumeGroupName...] DESCRIPTION
vgcfgbackup allows you to backup the metadata of your volume groups. If you don't name any volume groups on the command line, all of them will be backed up. In a default installation, each volume group gets backed up into a separate file bearing the name of the volume group in the directory /etc/lvm/backup. You can write the backup to an alternative file using -f. In this case if you are backing up more than one volume group the filename is treated as a template, and %s gets replaced by the volume group name. NB. This DOESN'T backup user/system data in logical volume(s)! Backup /etc/lvm regularly too. OPTIONS
See lvm for common options. SEE ALSO
