Always use different media from media pool - HP Data Protector

Hello..

I am using:
HP Data Protector ver: A.06.10 / 611 with HP LTO4 Drive (24 tapes)

I made 4 different "media pools" and added a minimum of 4 tapes to individual  pool.

I am wondering, how to Setup backup, that todays backup is writen on tape1, tomorrow  on tape2 ... tape3.... and not always on tape1

I our case, Data protector writes all backups to one tape until that tape is full..then writes to a different one

I've never used this particular software but on every other backup solution their is generally 2 times which can be assigned to a media pool - the overwrite protection date, and the append period date. If you set the media pool's append period to 24 hours , then in theory the tape is marked as not appendable after 24 hours, so it moves onto tape 2, and then 3. The overwrite value specified how long the tape shouldn't be written to again, in the above example it should be set to 3 days, meaning tape 1 wont be used again, until day 4.

As i said, im not sure how this software handles it, but this is a general constant on all backup software...

Pools can be appendable, appendable on incremental or not appendable, there is not time period options like that.

and do the pools have any notion of overwrite protection periods... as in when a tape is full how does it determine the next time it can be written too ?

If it is full, then he looks at data protection date for a client / backup job on the tape (actual data is protected.. media is not)

So in theory, set the tapes to not appendable, put them in the same pool. Set teh job data protected date to 3 days ? and then it will cycle throught he tapes 1 by 1 until it starts recycling....

Yes you would think so.. I must say that in theory it should work, if you have only one client/one job.
I have 6 different clients / 6 different backups in one day. So if i would done what you have suggested only one job per tape  and not "n" jobs per tape per day ?
