Can blocksize of restored backup be different?

Post by Duaner »

Hi,

We're using Veeam Endpoint Backup FREE as a desktop backup solution. The other day I was asked to confirm that when a system is restored (Bare metal or via restore -> entire volumes) the same block size is used as it was on the system the backup was taken from. I couldn't find this in the documentation.
The idea is to build a system from scratch (Win7 x64) on a ssd and create a backup on usb-hd before each program is installed. One is concerned that when the system is restored a different block size is used, which would decrease ssd performance.

Any ideas about this? Or, Where can I find this in the documentation?
Thanks

Hi Mark, the block size will remain in tact when restoring data from the backup file.

Hi Vitaliy, thanks for your reply. Does the same apply for the alignment of those blocks? Will that remain intact when restoring a backup?

Mark, VEB does not align data blocks automatically. To the best of my knowledge SSD block size is larger than the file system has, so I guess you shouldn't see any performance degradation, right?
