Larger than expected backup files

[networkn]

Hi.

So I installed Veeam Endpoint free onto my office PC, to test it. First backup went fine, was 60GB, about what I'd expect. The second backup ran and was 15GB. I assumed that was incremental and that perhaps it used block change technology similar to SP, but at 15GB I'm guessing not.
Is it expected that all subsequent backups, are going to be 15GB in size?

Hi AndreS,

What backup mode are you using and I wonder what ‘SP’ means

[networkn]

Sp = Shadowprotect

Volume Level Backup to a Shared Network Folder (I think that's what you are asking in terms of backup mode)

Thanks for the clarifications. Yup, VEB does use the change block tracking logic while performing an incremental backup. If the size of incremental backup is large – probably changes on the source disk have resulted this. That could be a file modification/file copy or even disk defragmentation.
