Hello all,
I have an HP SAS 8-slot robotic library using LTO5 tapes. My goal is to have full daily (including weekends) backups and have each tape devoted to one day each. I would like this due to ease of archiving tapes and finding tapes when a restore needs to be done. The 8th tape would be reserved for a weekly full that will eventually go offsite; we have a bi-weekly rotation of of weekly backups. This way, that magazines would only have to be loaded once a week and the offsite storage would not take one of my daily backups. I would also need to do a montly; this can be in place of the weekly if necessary.
Is this feasible? Should I go about this in a different way?
Tips/advice greatly appreciated.

If you want a Daily/Weekly/Monthly backup routine, then you need to consider a GFS policy...Grandfather/Father/Son.
It's simple and easy to setup. You'd create the GFS policy, which starts with the Monthly job being created. This includes your Append/OPP settings, naming your media set (or selecting a pre-existing media set), selecting partitions (if you use them in a tape autoloader/library) etc. along with naming this. You'd move on to the Weekly configuration, and then the Daily configuration.
Each is going to have its own media set. Different retention times mean this is required. No sense in having 1 media set for everything where tapes can be overwritten, and you end up losing a Monthly for instance.
Once done, select a selection list and you're ready to go.
I suspect what's happening is that you have 1 media set and are trying to retrofit a GFS backup strategy into this which won't work. A policy is easily managed & I'd recommend it. Tapes belong to media sets and are not used by others. If you have an autoloader/library, you can further segment the tapes physically by creating partitions.
Read the TNs below for further advice too...

This can be done. Create a media set with an OPP of 13 days and AP = 1 hr. Set all your jobs to overwrite and target this media set.
For the tape in the 8th slot, you should create another media set with longer OPP, but you should still use overwrite for your jobs.

You should let BE take whatever tape that it wants. It is a lot easier this way. Read my article below on why this is so.

As long as you have set up the OPP correctly, you don't have to worry that your tape would be accidentally overwritten.
As previously advised, overwrite is a job property.

If you have 2 sets of tapes, you can easily identify which set to use on which particular week.
As for using a particular tape on a particular day, do read my article referenced earlier again for why this will be a very difficult thing to achieve when you are using a tape library.

...I used partitions successfully, but only 3 (Daily, Weekly, Monthly - 5, 3, 1), but 8 partitions becomes a logistical nightmare. What happens if Tuesday's tape is put into Thursday night's slot by accident? BE won't span the backup to the next partition to search for an available tape. It will either queue (until a tape is imported, if you have an import slot configured) or fail.
Thanks!

For sure, and like I said, I used them...but 8 becomes a problem. Put the Wednesday tape into a Thursday slot, and like I said, the backup either queues or fails. Rather get the OPP/Append settings right in a case like this above (ie. NOT using GFS where you can have more slots in a partition) and not use partitions.
I know some people would advocate this over partitions, and in this specific example so would I.
Thanks!

Well, how is your job set up? You're obviously not using a GFS policy, so it is 7 days of full backups with no weekly or monthly.
You can do any of the following:
1. Create a second set of 7 day backups and move tapes into a new media set. Then just make sure the 2 sets are kept separate;
2. If you lock up the tapes, designate space for both sets of 7. Just label them MOnday 1, Tuesday 1 etc...Monday 2, Tuesday 2 etc.
3. Use a spreadsheet to track which tapes were used and when.
Thanks!

GFS = Grandfather, Father, Son = Monthly, Weekly, Daily. Do you have this?
If this is right, what days do you run your Daily, Weekly, and Monthly backups on?
My GFS policy (when still an engineer) was as follows:
1. Daily - Monday --> Friday (Slots 1 --> 5)
2. Weekly - Saturday (Slots 6 & 7)
3. Monthly - Last Saturday of every month (Slot 8)
This worked well across 29 sites I looked after, and the site engineers knew what tapes to put in when as the Daily tapes were designated as Daily Set 1 (1 --> 5), and Daily Set 2 (1 --> 5).
The Weekly tapes (3 of them) were easily rotated.
Thanks!

I now have a true GFS policy. But now I cant get the job to do anything. Just queues.
I can see under devices, in use, idle, in use, idle......

Okay, now all errors aside; we are now backing up using a true GFS and letting BE take whatever tape it likes.
Now I have another question. I noticed the job report shows that BE used more than one tape for the same job. Does it simply fill up the tape then move on?
If so, this will not work. I need to be able to keep daily onsite, weekly will leave and return bi-weekly, and montly will never return. That said, weekly and montly must be on one tape, and must be the only thing on tape. How can this be done?
In other words I cannot have a tape that has a weekly and a monthly; that tape would need to be returned and stay off property permenently. Or have a daily and a weekly mixed where weekly is currently offsite, but need it for a restore for the daily portion.

...unless your backups are a lot smaller and can fit onto a single tape, then chances are good that you're spanning 2 tapes.
Furthermore, the idea behind having a Weekly/Monthly backup (or GFS policy/setup) is that Daily/Weekly/Monthly backups have different retention times. Putting 2 different backups onto 1 tape defeats the object of that, and there is no way to have 2 retention times on a tape.
Simple solution is to have enough tapes to do the job properly.
Thanks!

I have plenty of tapes. I want to know how to keep multiple jobs off of what ever tape becomes the monthly.
Im not putting two different backups on one tape, BU is. Letting it take whatever tape, as recommended.
So my question still stands; how can I ensure that only monthly is on the monthly tape?
