Hi there, I have been struggling with UrBackup for a couple of weeks. Near the end of February, I noticed that incremental file backups were taking a very long time (used to take 5 minutes, now take 8-20 hours for the same amount of data). I can’t remember changing anything about my installation at that time. My clients are on Win10 Pro & Home, the server is on Ubuntu 16.04 ZFS. Clients are running 2.1.15, server is running 2.1.19 (latest versions). My backups are not running on low priority, and CPU/hard drive/network utilization is well below capacity.
Live log has a lot of this (for files which are already backed up on the server and have not changed):
"Loading file ..." "PT: Hashing file " "HT: Copying file: "...""
I took a look at a single file which I know hasn’t changed for a long time, and listed it within all my backups. The second column is the hardlink count. Everytime it changes is when I started a new Full Backup (I think). Scroll to the bottom and notice how after the 2/24, the hardlink count drops to 1 with every subsequent incremental. Additionally, the file modification time is not preserved (it’s May 28 2014 on all the old backups, like the source file, but the times are different with every subsequent backup after 2/24). I looked carefully at other directories and it seems that only small files (less than exactly 2048 bytes) are affected. I believe the software regression occured on the 2.1.19.1765 version rolled out on 2/25/17.
Thanks!
