2 drives for backups

[VILLALOBOS]

Hello All , I need your help , I need active 2 drives in this moment only one work, How cai I make this ?



EXAMPLE :

#!/bin/sh
# filename: /backup/script/osbackup
#
# This script will back up the Oracle and SAP executables
# to tape device rmt0h using the AdvFS vdump utility.
#
# Prerequisites: write-enabled tapes in drive rmt0.
#
# The SAP instance must be shutdown to perform this backup
#
INSTANCENAME=SP1
ADMACCT=tstadm
LOGFILE=/backup/log/bdofflinebkp.log
TAPE=/dev/rmt0h
NR_TAPE=/dev/nrmt1h

#
# Resetting the log file for backup
#
if [ -f $LOGFILE ]
then
mv $LOGFILE $LOGFILE.old
touch $LOGFILE
fi
echo "Ready to start backup at `date`" >> $LOGFILE
echo >>$LOGFILE

Hi,

If you're just using the OS built in command vdump, then you'll have to identify which file systems can be backed up at the same time, and then start off two simultaneous vdump commands, one on /dev/rmt0h and one on /dev/rmt1h.

If you don't know how to do this, then try posting the rest of your backup script and we'll see if we can help.

It would also be useful to know what version of Tru64 you're using.

Hope this helps,

Regards,

Rob

Hi Rob, this is a script




#!/bin/sh
# filename: /backup/script/osbackup
#
# This script will back up the Oracle and SAP executables
# to tape device rmt0h using the AdvFS vdump utility.
#
# Prerequisites: write-enabled tapes in drive rmt0.
#
# The SAP instance must be shutdown to perform this backup
#
INSTANCENAME=SP1
ADMACCT=tstadm
LOGFILE=/backup/log/bdofflinebkp.log
TAPE=/dev/rmt0h
NR_TAPE=/dev/rmt1h

#
# Resetting the log file for backup
#
if [ -f $LOGFILE ]
then
mv $LOGFILE $LOGFILE.old
touch $LOGFILE
fi
echo "Ready to start backup at `date`" >> $LOGFILE
echo >>$LOGFILE

echo "Done."
echo "backup finished at " `date` >>$LOGFILE

echo "Please remove tapes from system" >>$LOGFILE
exit

OK. Create two copies of this script.

In one of them define:

TAPE=/dev/rmt0h
NR_TAPE=/dev/nrmt0h

in the other define:

TAPE=/dev/rmt1h
NR_TAPE=/dev/nrmt1h

Then based on the amount of data in each of your filesystems, split the vdump commands between the two. For example you might want to put sapdata1 to 7 in the first copy of the script and sapdata8 to 15 in the second copy.

Can I use the two drives one by one for the same script? I need put in the cron this backup .. There is a not problem if I run the 2 scripts in the same time?


Thanks for you help, realy many thanks

I am learning this system ...

[Rob Leadbeater]

Hi,

There shouldn't be any reason why you can't run both scripts from the cron at the same time.

Rob

Just realised as I'd typed that, that you'll probably want to make the LOGFILE name unique to each script.
