ufsdump backup duration
hi, i'm trying to figure out how to tell the amount of time a ufsdump of a directory takes. i use the below command:
echo "Starting Backup of u4" >> /backup/backup.log 2>&1
/usr/sbin/ufsdump 0uf /dev/rmt/0n /u4 >> /backup/backup.log 2>&1
echo "Finished Backup of u4" >> /backup/backup.log 2>&1
date >> /backup/backup.log 2>&1
mt offline >> /backup/backup.log 2>&1
my problem is, after the script prints "Finished Backup of u4" to my log there is a big gap for when the date command prints as can be seen below:
DUMP: DUMP IS DONE
DUMP: Level 0 dump on Fri May 28 05:36:06 2010
Finished Backup of u4
Fri May 28 08:14:46 AST 2010 <-- this was echoed by the "date" cmd
did my ufsdump finished at 05:36:06 or 08:14:46?
---------- Post updated at 09:44 AM ---------- Previous update was at 08:43 AM ----------
i think i found the answer. i think it's the time difference between the ufsdump.
for example, if my first ufsdump today is 08:00 and the next ufsdump is 09:00, then my first ufsdump backup took an hour. am i right?

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.
