I’m kicking the tires on urbackup on my TrueNAS Scale system, backing up a handful of directories from a remote linux machine. I’m taking a full file backup every 30 days and incrementals every 5 hours. The cadence seems to be correct, but in digging into the incremental folders I’m seeing full copies of unchanged files in each rather than symlinks to the original in the full file backup. Is this expected behavior, or do I have something configured improperly?
Your issue seems to be similar to mine.
Indeed, seems like the same issue. I don’t see any flags or parameters to set that would change the behavior, this seems intrinsic to how it operates.
It’s either a bug introduced in newer versions, or most likely something is tripping hash comparisons. For the files that are duplicated in my case, I don’t have a prior reference to those in the urbackup database and hence no hash to compare to, if in fact that’s where the hashes are. I suspect at some point the database got corrupted or cleanup may have removed something… still trying to figure out what’s going on.
