Everything about backing up to tape

Question about multiple tape drives

Veeam Logoby mvierling » Fri Oct 11, 2013 2:08 pm

I have two Quantum LTO4 tape drives. In Veeam, they show up up as:

Quantum LTO 4 Tape Drive (Tape 0)
- Drive
- Drive 1

Quantum LTO 4 Tape Drive (Tape 1)
- Drive
- Drive 1


Instead of
Quantum LTO 4 Tape Drive
- Drive
-Drive 1
-Drive 2

The problem this creates is that I would like to have tapes inserted into each drive and then when my copy backup jobs runs, it will automatically roll over to the second drive when the first drive is full. With how they're being recongnized now, that is not possible because each drive has its own Media Pool information that the other drive does not see. Any ideas on how to accomplish what I'm trying to do?

I contacted the support team and they said to post in the forums to ask as a feature request.

Mike,
I am sorry, I missed the last line and for me it looked like "Tape library and drives are shown as separate devices" known issue. Currently, yes, media pool is 'attached' to each library and there is no way to accomplish such scenario. However we will look into your case and discuss it with the team - that you for feedback and once again I am sorry for misleading.

Hi
Any update on this, I have the same issue. Will it be resolved in v8?

Thanks

Steve,

The media pool behavior is not going to change in v8, so it is still linked to the tape library. As for the tape drives and medium changer displayed separately in the VBR UI: we enhanced “device tracking” mechanism, but there is no 100% guarantee that this change would apply to all the tape hardware in the field. So we still have the related KB article, which is still a perfect fix: Tape library and drives are shown as separate devices

Hi
I do not have that registry key? Can I create it manually?
Mine is not a tape library, but 2 individual tape drives connected via SAS.

Thanks

Yes, you should create it manually.

Can you elaborate on that? What particular problems you experience? You don't have a tape library, but instead two tape drives? If so, the corresponding article is unlikely to help, as it's primarily concerned with tape library's incorrect recognition.

Thanks.

Ok I created it manually and it didn't change anything.

I have 2 identical, but separate single tape, tape drives, both connected via SAS. Normally in BE or another backup program you would be able to add the tapes from both drives to the same pool, so when the one tape drive got full, it would carry on on the second tape drive, but I can't do this in B&R.

As I've said, the said article is unlikely to be helpful, since is supposed to help in situations when tape library is recognized as different devices. In regards to your issue, currently it's impossible to use multiple drives within one media pool and you have to create one media pool per drive. Thanks.

This is really something that needs to be addressed, as it is a common requirement. I am very disappointed that it will not be resolved in v8 as it now means I need a separate backup product, as my backups will not fit onto one tape.

Your voice is counted. Bear in mind though, that priority is given to top requested features (those typically have several page long topic discussions). However, can you elaborate on how the ability to use multiple drives within same media pool will allow you to fit all your backups to one tape medium? Thanks.

It wouldn't fit onto one medium, but it would allow me to span to a second tape once the first tape was full, without having to manually change tapes.
I realise most people would have tape libraries for this, but it was a conscious decision on our side.
We didn't want a tape library failing, and to then be stuck with no tape backup what so ever, as this has happened before. So we decided to rather have 2 individual drives so we could continue to back up if one failed.
We just assumed B&R would be able to have tape pools that could span multiple tape drives.

Got it. For now the only solution I can think of is to divide existing backup job into smaller ones that might fit into one tape. Then, create one tape job per one smaller backup job and point them to different media pools. Thanks.

Hearing that this issue will not be addressed in v8 is quite disapointing. Backup to tape is still a "best practice" and for certain situations mandatory (e.g. legal archiving of DMS content to WORM media).

So please add one customer to the list of people who need to use multiple tape drives (identical or different models/capacities) as a JBOD to automate their backups without turning towards a tape library.

Thanks
