HP StoreOnce shares to catalyst stores

Veeam Logoby andriktr » Mon Jan 18, 2016 7:38 am

Hello,
I have question about HP StoreOnce catalyst. At this moment we use HP StoreOnce shares as backup repositories in Veeam B&R 8. Planning to upgrade to version 9 soon.
But it’s still unclear for me how to migrate our existing data from share to catalyst stores and configure existing jobs to use catalyst.
The only note that i have found about in the new user guide was:
"If you have added HP StoreOnce shares and stores as backup repositories in Veeam Backup & Replication 8.0, after upgrade to 9.0 these stores and shares will be presented as shared folder backup repositories. To use the HP StoreOnce Catalyst technology, remove these shares and stores and add them once again to the backup infrastructure"
Thank you.

Andrej, the recommended way to migrate between CIFS and Catalyst Store is as follows:

1. Add the StoreOnce device as new Catalyst repository.
2. Clone existing jobs that point to CIFS share.
3. Change target repository in the cloned jobs settings, pointing them to the newly added repository.

This will trigger active fulls on all these jobs and create completely new backup chains, however this is still required for the new per-VM backup chain feature (which is mandatory for StoreOnce Catalyst repositories due to its current inability to provide concurrent reads) to take effect.

What do you mean when saying "clone the data" you should clone only jobs change target repository in the cloned jobs settings, pointing them to the newly added repository.
You can't use old jobs (backup data) point them to catalyst stores and copy old data.
You should create new job that means new backup chain.
In some cases, for example if your old jobs have long retention policy, this scenario sounds not very good because you will need to manually manage/delete backup files which are out of backup retention policy

Right, you do not need to copy existing data to the new Catalyst repository. Though, there are workarounds to do that, we still recommend to start chains anew, to enable per-VM chains. Existing backup data can be left aside in old repository until it reaches the retention and then be deleted manually.

How about backup copy jobs with GFS retentions? Your recommendation to create new jobs also valid here?

Yes, this is a global recommendation for StoreOnce repository.

[MERGED] : How to move existing backups to HPE StoreOnce dev

Veeam Logoby DaveWatkins » Fri Jan 29, 2016 2:26 am

Is there any process for moving existing backup data from, for example a windows repository to a StoreOnce dedupe device when using it in Catalyst mode?

There doesn't appear to be any way to copy to the StoreOnce manually, and Veeam doesn't seem to have any way to automate the process.

On that note, it would be _really_ useful for Veeam to be able to migrate existing backup data from one repo to another (including the custom dedupe devices) without having to go to the repos and manually move the data then map it into the backup job

Don't really have an answer about the StoreOnce part but for this you can use Scale-Out Backup Repositories and put repositories in maintenance mode and evacuate backups so we move everything for you around.

Re: How to move existing backups to HPE StoreOnce device

Veeam Logoby nefes » Fri Jan 29, 2016 8:06 am

You could find several creative workarounds (including Evacuate) to move backup chain to StoreOnce Catalyst.
However it is highly recommended to use completely new chain.
Main reason for this is Storage Per VM option. It is not accidental decision to make this option mandatory for StoreOnce Catalyst:
This store supports exclusive read only. So If you have large vbk with tens/hundreds of VMs you can't restore two of them simultaneously. And even some Backup/Backup Copy activities will fail due to inability of concurrent read.

Try it, and you will be surprised by active full speed with necessary paralleling in place.

Dave, your post has been merged into existing discussion. Take a look at the answer provided by Foggy for the description of recommended approach. Thanks.

To start with, the ScaleOut migration doesn't work. No explanation why, but it doesn't (in practice). And while I totally understand the desire to get things migrated by using a new per-VM chain, this does NO GOOD when trying to seed a remote copy.
There is a copy/paste function in the UI (look under Files and you'll see the StoreOnce repos and be able to do some minimal file manipulation on them). They are no, however, valid targets for a File Copy job, and I've found hit-and-miss results (mostly miss) with trying to copy large files over to the Catalyst store: horrible errors thrown when trying to rescan the repository or open the backup for recovery or adding a new incremental to the chain.

Hi, Jim. Do you have support case ID for these two issues you mentioned? This is something I'd certainly like the corresponding QC to take a look at. I am even curios because these migration scenarios were ready in advance and very well tested (in other words, it was not an afterthought use case). Thanks!

I'm planning on opening a case for the latter (the copy+paste for seeding a copy job) but haven't yet due to other constraints. I wasn't going to worry about the former because it's a sub-optimal option: it really does have a positive impact on performance & dedupe/compression on the StoreOnce to leverage per-VM storage, and simply migrating a monolithic VBK+VIB chain will never get you there...
