Noob question about vmdk backup

Post by karnalta » May 19, 2019 8:30 pm

Hi all,

I am currently saving a large VM (2 Tb) with Veeam Community Edition.

While backup job was running, I remembered that there were 500 Gb of completely useless data on a VM's disk. So I deleted them while backup job was still running.

It didn't seem to have any influence on the backup time so I wonder myself, how does this is handled by Veeam ?

What happen if data wasn't backup yet ? What happen if it was currently working on that vmdk or if that vmdk was already backup ?

Thank for lighting me up.

Hello,
everything you do after the snapshot has no influence. As you wrote "while backup was still running", I would say "no influence" as I guess you were not fast enough to do that between job start and time of snapshot :-)

In general: If it is a Windows VM with NTFS, then see bitlooker feature in user guide

Keep in mind that we do image level backup. It's block based. We don't to file level backup (you might have done before as you ask a question which makes most sense for file level backup).

Best regards,
Hannes
