[EN] file ownership: fuse

[jyp]

Hi
As I prepare to drop luckybackup and use backintime (as suggested by @devil), I  was revising my backup structure and noticed that most of the time, the owner was me (jy) but the group was _fuse_.

I tried to find out why but found nothing really relevant googling the subject. Is it better to use _fuse_ as a group or should I replace it by me (jy)?

Also when I create a directory (000-test), the ownership comes out like this
drwxr-xr-x  2 jy   jy    4096 mar 23 11:28 000-test


Here are some snippets from my system

/home/jy$ ls -l

Thanks for any clue.

Where did you see this? It does not happen in backintime for me, everything belongs to my user, as it should be in /home. That is all I back up. The rest gets imaged by CYA on the main box and Btrfs/Snapper on the notebooks.

@devil
Nothing happened in backintime yet because I did not run it, just exploring.
I am just wondering how the group id became _fuse_ as I, for sure, did not volontarily assign this group to the _directories/ subdirectories/files_ that I created. Now this group id is everywhere.

But when I create a new directory or a new file, it comes out with normal ownership. For instance

Code: [Select]

...:/hdd01/data$ ls -l
total 104
drwxr-xr-x  2 jy   jy    4096 mar 25 13:51 000-test

...:/hdd01/data/000-test$ ls -l
total 0
-rw-r--r-- 1 jy jy 0 mar 25 13:53 test-file.txt
I am the only _user_  (jy) on that machine.

Would it be better practice to get rid of the _fuse_ group and put back _jy_ ? Is there a reason that _fuse_ has been assigned?
Just trying to understand.

Thanks.

This is the state of my system.
