Incremental Backup Sizes are HUGE (over 100gb a day)

Hi all,

We have a file server that does very little in terms of usage. However each day the endpoint backups are over 150-200gb. There is just no way that this site is generating that amount of traffic. So something must be causing veeam to backup so much data.

Has anyone has similar situations in the past? What was it? I thought it might be indexing (it is a 2008 R2 server) but the role is not installed.

Cheers,
Aaron

Have you got schedules shadow copies set up? What about regular defrag?

Aaron,

I see that you have 210 GB of changes on your C-drive and 18.8 GB of changes at the D drive. That is quite a lot. Are there specific applications that make a lot of changes? Any idea what changes so much?

You say that it is not changing a lot, but there must be something that really changes a lot! If you really don't have a clue of the amount of changes, please log a support call so our engineers can verify what is happening (through the UI)

Thanks
Mike

hi Mike,

There is nothing that comes to hand as we have a couple of these servers deployed in similar configurations but as you say, something is obviously touching files left right and centre. 210gb does sounds like something that is moving through the file structure doing 'something' you would have to think. defrag doesn't run, and shadow copies are turned off.

I'll just log a support request, its the easiest option.

Cheers,
Aaron
