I have a network of 15+ computers we are backing up. All windows clients use the cbt client 2.1.19-cbt
I have one of these windows clients that I am doing a daily file backup on these locations and a weekly image backup of whole system.
C:\Users\username\AppData\Local\Microsoft\Windows Live Mail
Weekly image backup works great but on this system alone the 42.2 gigs contained in the above directories shows as 401.59 gig backup. Every day. The physical hard drive that this filesystem is on is only 232 gigs in size.
File backup takes around 16 hrs for that client.
here is log from that client showing yesterdays backup

I am pretty confused on this issue and not sure what to do.
Server is verson UrBackup 2.2.11 running on Ubuntu 18.04 and the raid 10 that the backups are stored on is formatted as BTRFS. Client confirms that CBT is enabled on the partition that these files are being backed up from.
All other clients are backing up correctly except 1 that is windows 2003 R2 32bit I will address that in a separate post
