How to exclude subfolder

[TmPostPrtt]

Hey, here an example of my problem :

• MyFolder
  • Sub1
  • Sub2
  • Sub3, etc...
  • File1
  • File2
  • File3, etc...

I would like to exclude Sub54, is it possible ?

You can use BACKUP_EXCLUDE_REGEXP which matches the full filepath:

# When given, all files in BACKUP_SOURCES whose full path matches the given
# regular expression will be excluded from the archive. Regular Expressions
# can be used as from the Go standard library https://pkg.go.dev/regexp

# BACKUP_EXCLUDE_REGEXP="\.log$"
