Full Discussion: Newbie Backup Script
Operating Systems OS X (Apple) Newbie Backup Script Post 302548536 by xbin on Thursday 18th of August 2011 04:26:06 PM
Old 08-18-2011
I see posibly two issues; the device disk number could change and the uncanny ability of OS X to write directorties that aren't mount point to the /Volumes directory. So first I would query diskutil and mount for the proper device then run something like ->
Code:
for MNT in /Volumes/*
do
if [[ $(/usr/bin/stat -f "%d" "$MNT") = $(/usr/bin/stat -f "%d" "$MNT/..") ]]; then
 echo $MNT is NOT a file system mount point
fi
done

vgcfgbackup

VGCFGBACKUP(8)                                                System Manager's Manual                                               VGCFGBACKUP(8)

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.
