vdump question
I have a question about vdump utility.
Nowadays my backup takes almost 3:00 hours to be completed.
Is there any parameter to make the vdump a bit faster ?
Here is the script i use to do the backup
Any comments will be appreciate.
#!/bin/sh
#/sbin/vdump -0uf /dev/nrmt0h /
# /dev/nrmt0h = DLT
#
echo "=================================="
echo "| BACKUP PARA D L T |"
echo "=================================="
echo " "
echo "*** VOLUME 0 ***"
/sbin/vdump -0uf /dev/nrmt0h /
#
echo " "
echo "*** VOLUME 1 ***"
/sbin/vdump -0uf /dev/nrmt0h /usr
#
echo " "
echo "*** VOLUME 2 ***"
/sbin/vdump -0uf /dev/nrmt0h /db_prod
#
echo " "
echo "*** VOLUME 3 ***"
/sbin/vdump -0uf /dev/nrmt0h /bi_prod
#
echo " "
echo "*** VOLUME 4 ***"
/sbin/vdump -0uf /dev/nrmt0h /dump_load
# TAPE REWIND AND OFFLINE:

Re: vdump question
It is also important that the tapes/disks are fast enough to write/get the data just in time to tape/from disk and not in stop/go mode waiting for data (due to I/O bottlenecks)
So a real backup software is mandatory for professional environments leading to reduced backup times and compatible backup mechanism in case of hardware outage.

Re: vdump question
a backup is always necessary, but if you backup a huge amount of data every day use a professional software and not a simple OS tool.
There are so many tools out.. Veritas, Legato Networker, Amanda etc.

Re: vdump question
I have checked into my system to see if i have the "legato"
Under the /opt directory i have a legato directory.
How do i know if my backup is using the legato software ?
Or how do make the legato software to start working as my back utility.
Many thanks
Regards

Re: vdump question
check what version of legato is installed (setld -i |grep LGO). If starting nwadmin there should be no error message.
Btw. have a look into the documentation (legato will not be configured automatically and requires additional knowledge about the legato concept etc.) or remember what you have installed with the OS. Maybe there is a backup policy in your company and other people installed/enabled legato on your machine.
Some versions contains a single server legato edition, have a look into the release notes of your distribution.
