ReFS: Moving Backup Copy Job to new ReFS Repo

Veeam Logoby doggatas » Mon Sep 04, 2017 10:33 pm

By the nature of Block Cloning the most disk space savings are had on the Full Backups. I need to move a bunch of GFS backups to a new Repo. If I have a Backup Copy Job sitting on a ReFS repo is there anyway I can move those files to another ReFS repo (different volume) and retain the space savings or once I copy those files off the ReFS volume they were created on, are they always written at their full size at the destination?

Regards,
David

Hi David, it's the second, copying files to another volume inflates them.

Thanks. I will start a new backup chain on the new repo.

Will that change in V10? I mean it is not really that unlikely that with a long GFS chain you have to change the hardware at some point and then you will loose all the space savings...

It is actually not specific to Veeam B&R, but to ReFS itself (think like volumes with Data Deduplication enabled).

I know - but can Veeam not find out if a block is cloned and move it with the reference to the new block address on the new volume?

No, there's no such copying functionality in Veeam B&R.

@mkretzer it's worth noting that the feature you are asking about possibly being added to Veeam v10 would more usefully be requested of Microsoft as a possible enhancement to the ReFS engine. Like @foggy mentioned, it's analgous to a volume that has Data Depulication enabled, where copy/move actions to other volumes will trigger 'rehydration' of de-duplicated data. Solutions to this are

1. Start a new backup chain, as original poster has opted for in this scenario.
2. Assuming sufficient available storage ( and IOPS capacity plus CPU time) on the new volume, copy the data from old volume to new volume and allow the rehydrated data to go through deduplication again.

Neither of these are pain-free scenarios, but thats why we pay careful attention when we do our capacity-planning work to avoid having to do too many storage-platform rip & replace operations, right?

Hi there

There are a couple of times where it would be nice if Veeam had a "Move existing backup jobs intelligent":

-Migrating jobs from one REFS volume to another without re-hydrating them
-Rebuild the second or third copy with GFS jobs
--When a data loss occurs it would be nice to set Veeam to recopy the GFS points
---if the second copy is encrypted its not possible just to copy the local files since they aren't encrypted
-Move from one service provider to another without loosing GFS history

Have a nice day,
Henrik
