Right this may be a bit long, but i would really be appreciative of some
help.
Ok
First info is i run netbackup 3.2 on Solaris 8 with an L1000 sun 30 tape
unit.
I admin backups for a client and there are 2 sites. A production site and a
dr site ( disaster recovery )
Now for simplicity i will say i have 4 machines on each site. + the backup
servers
production dr
prodbackup drbackup - backup servers
prodapp1 drapp1
prodapp2 drapp2
proddb1 drdb1
proddb2 drdb2
On production site i run a dr class which backs up data only, ( the OS is
covered under a differnt class etc )
I also backup the /usr/openv/netbackup/db and /usr/openv/volmgr/database
directories with below script ran from cron daily.
#!/bin/ksh
#Dave M
#Backs netbackup databases up to disk to ftp to DR site
PATH=/usr/openv/netbackup/Backup_DBs
COMMAND=/usr/openv/netbackup/bin/admincmd/bpbackupdb
LOGFILE=/var/netbackup/backupdbs.log
echo "Backing up Netbackup Databases on `/usr/bin/date`" > $LOGFILE
$COMMAND -dpath $PATH >> $LOGFILE 2>&1
/usr/bin/ls -l $PATH >> $LOGFILE
echo "--------------------------------------" >> $LOGFILE
This creates 3 files in =/usr/openv/netbackup/Backup_DBs HEADER, IMAGE1
and IMAGE2
I copy these by ftp to the dr site each day.
Now i need to perform a recovery operation and beable to restore onto the dr
site data from the production site in the dr class.
The architecture on both sites is the same as the servers are identical,
just different host names and the proddb and drdb machines are running
cluster and have a different logical host path structure.
I was thinking i could somehow load the databases i have ftped to the dr
site into the dr site netbackup which would mean the L1000 and netbackup on
dr site would be able to recognise the dr class tapes i put into it which
have come from the production site.
The dr site backup server knows about its clients obvioulsy, but i was
thinking how will i beable to restore things from the production site
machines to the dr site machine equivalent.
I know this may not make much sense but if someone could help i could give
extra info as required. Please please
Dave ( a desparate man )
