The shell script will check if there is enough space to create a snapshot

Hi,
There's been discussion before on this list on the very small number
of hard links supported by btrfs.[1][2] In those threads, an often
asked question has been if there's a real world use case the limit

Also, I believe it's not strictly 256 links, it's dependent on the length
of the names.
I recall Chris posting something about being able to fix this without a
format change, though it wasn't a priority yet.
As to my knowledge the limit is 64KB for all names of a single file and due to

That means it would not work for my backup server.
At 4 backups per day, failure for filenames with 45 characters after just

IIRC, the limit on hard links is per directory. That is, if you put
each hard link into its own directory, there's basically no limit to
