Hi,
Is there anything faster than
rm -rf
?
I'm using rync with the --link-dest= option.
Since this option uses hard links extensively, both, and
have to be
on the same file system. Therefore, just re-making the file system
anew, cannot be used.
There are more than 55,000 files on som

I don't have any solid suggestions as I haven't used btrfs in a while.
And honestly, expanding on what Rich said... Given your particular
circumstances with the extensive number of hardlinks are pretty
specific, I reckon you might be best off just setting up a small scale
test of some options and profiling it. Converting it all to a btrfs
subvolume might be a realis

It is lightning fast on lizardfs due to garbage collection, but

The real solution would have been having a subvolume for the directory.
Subvolume deletion on BTRFS is near instant.
Same for ZFS with datasets, etc.

Thanks!
Is it possible to have a hard link from one subvolume to a different

You could do a quick test, but I don't think so. I haven't used btrfs
in years but they're basically separate filesystems as far as most
commands are concerned.

Many thanks to Rich, Miles, Vitor and Laurence for their hints on this
subject.
Especially the suggestion to use BTRFS Snapshots was very helpful.
Finally I have come up with the following shell script for backing up
my /home directory,
comments are more than welcome, of course.

Is /home on btrfs? If not then something like this is p

I think there are tools out there which already implement this for
btrfs.
I personally use:
