Most WAN-friendly backup mode for object storage?

Post by armstrongr »

Hello all,

I have just started testing for my company moving from backup to tape with V9 onto backup to Azure blob storage with V10. Until now we have used Incremental backup, with synthetic full backups created weekly (for a full write to tape) and previous backups transformed into rollbacks. My company policy on DR is to keep 4 weeks rolling backup so this setup works well.

Moving onto V10 and Azure blob storage, I see in testing that it causes a full size transfer which will be impossible to transfer within a week at most of our sites. With this in mind, should we be moving away from using the weekly synthetic full, and instead using reverse-incremental?

I've seen a couple of threads similar to my question, but not quite the same, so wanted to check if I was going about it correctly.

Thanks in advance.
Rob.

Hi, Rob. Our object storage integration is forever-incremental regardless of the source backup chain type. Thanks!

Hi Gostev

Just to confirm, does that mean the large transfer behaviour I see in our PoC should be resolved with the bug-fix I've seen mentioned? If so, I will register a case with support to get notified on its release.

Since you're using periodic full backups, you're not affected by the said issue and the hotfix is not relevant to you.

If you see that full backup gets re-transferred to object storage on weekly basis, kindly, open a support case and post its number here.

Thanks!
