I do a nightly backup of the music on my NAS. Most of the time, nothing changes and a backup looks like this:
using parent snapshot 10a72eb3 Files: 0 new, 0 changed, 32782 unmodified Dirs: 0 new, 3 changed, 2613 unmodified Added to the repository: 1.541 KiB (1.042 KiB stored) processed 32782 files, 520.483 GiB in 0:14 snapshot db5ec6c6 saved
So 3 directories changed. I wanted to figure out what actually, so I did a diff between the 2 snapshots:
comparing snapshot 10a72eb3 to db5ec6c6: Files: 0 new, 0 removed, 0 changed Dirs: 0 new, 0 removed Others: 0 new, 0 removed Data Blobs: 0 new, 0 removed Tree Blobs: 3 new, 3 removed Added: 1.541 KiB Removed: 1.541 KiB
According to this, no directories were changed, only tree blobs. How do I find out what really changed?
I ran the diff again, this time with --metadata. It showed that the 3 directories leading up to the music directory changed:
/home/ /home/fortemezzo/ /home/fortemezzo/data/
But since I’m not backing up those directories (the directory I’m backing up is /home/fortemezzo/data/music/), shouldn’t changes in those directories be ignored?
