Size backup Veeam 8 Vs Veeam 9.5

Post by SatMDOR » Oct 30, 2018 9:46 am

Good morning,

I leave this post, because we have migrated from Veeam 8 to Veeam 9.5 and we have seen that the (new) copies of the same machines occupy less than half, this is normal or something is doing wrong, the same happens in the 100 machines of which we make copies.

I have tried to recover the machines or files from them and it does not do without problems.

Thanks greetings!

Can you check whether this setting is enabled in backup job advanced storage options?
it does not do without problems.
I assume you meant that you'd restored without any problems, right?

Thanks!

If I have restored files without problems but it seems strange that the copies occupy half, it has improved so much?

What about the mentioned setting? Is it enabled or not? The feature (that has not existed in VB&R v8) allows us to get rid of dirty blocks present inside VM, which should result in significant backup size reduction. Thanks!

Actually, that option was not active in VM8 (although I have not seen it) and instead in VM 9 it comes out as recommended by default what surprises me is that it can be reduced so much

It didn't exist at the time of VB&R version 8.

Since that time not only has this feature been introduced, but also it has become quite mature to an extent where we recommend it as default option. So, it must be the reason for the backup size reduction.

Thanks!
