Re: Antwort: Re: each dbbackup to new tape?

OK, I just have to jump in. If I understand Hoa he:
1) Backs up the TSM database to a disk file
2) backs up that disk file to a TSM disk storage pool using DSM
3) moves that db backup to onsite/offsite tapes using "backup stg" and
migration

If this is so, then what do you do when you have lost your current TSM
database?

In Hoa's case, I guess he can get restore a copy of the db backup from
his server located 11 miles away, if he has vaulted the files their and
that server can restore an that individual file from those "vaulted
tapes".

If however Lucian's case is more typical, having only one hot server,
then I believe your restoration procedure consists of telling your boss
you lost the entire TSM server along with all backups and then posting
your resume on monster.com. Of course you may not want to mention your
most recent employment.

Hi Hoa,

now this sounds interesting: I suppose I willhave to define a
"FileDrive"
device, since I belive that only device classes are allowed targets to
the dbbackup command. And then set up a nice small storagepool so the
file gets instantly transferred to tape...

Thanks for all responses to my question

Regards, Lucian

Lucian,

This is what we're doing to save 3592 tapes:

Incremental backup and full DB backup go to flat files, shift those
files to offsite or onsite to Disk Storage Poll and let migrate
functions put them on tapes.
(We have servers onsite & offsite 11 miles away for disaster).

Hoa.

each dbbackup to new tape?






Hi list,

I'm rather green with TSM, actually working through my first
client-project with it and have come to a (small for sure) problem
System: TSM 5.2 on SuSe SLES8, feeding an Adic Scalar24 with one
IBM-LTO2.
Basically, the system works.
Whenever I command a dbBackup, wether full or incremetal, TSM wants to
write to a scratch tape only. If i give the volser of a tape used for an
earlier dbbackup explicitly, TSM says the tape is full (which it is
not).
Can someone point me to the right direction?
