What is average incremental backup size?

1

Just wondering what every is seeing ‘on average’ across all their clients, for backup size?

My clients are all Win8.1 / Win10… fairly standard setup… Office 2013/2016… no overly large local database programs or anything (School Teachers, basically)

I now have 21 clients successfully doing backups… and using a total of 1tb of space on the server
I am only doing File backups of C:\Users* and D:\Users* (if it exists) - no Image backups
Exclusions are: *\Temp*; *\Defender*; *\Microsoft Antimalware*
Clients range from 7, to 180gig of backup size

the main question is: Incremental backup size…

I’m seeing - on average (just eyeballing all the client backups list) around 500meg per incremental
(every 5 hours)
Some are as high as 1gig
others are as low as 200meg

what are other people seeing on their clients?

is it worth tweaking the exclusions a bit more?

I’m not pushed for space, but I don’t want to have it runaway!

Push the exclusion with at least filters for browsers temp data.
Maybe try to put log on verbose to list the backuped files, then add the ones you dont want to the ignore list.
Or make a windows seearch for files created/modifier less than 5h ago

On my linux i have a list of about 200 exclusion (already made a request for enhancement to have a larger ignore list inpout box in urbackup)

anyone got a canned list of common exclusions for windows… save me re-inventing the wheel? :slight_smile:

The setup wizard after client installation creates a pretty long list. You could run it on one client and copy that one.

Slightly modifed list here:
added new lines for readability
replaced usernames with : (i guess the wildcard for a dirname)
replaced sysvol names with a wildcard

I pushed the notray install silently via GPO… so might have to do a manual install?
