I need the -hash param for one file in my backup, a Vera Crypt Container. Do I really have to create an entire new Backup Repository for the single file, so I don’t have to run backup -hash over every file?
Or is there a possibility to run the backup with the -hash algorithm for selected files?
Would be an interesting additional config option then… 
The ideal way would be to add a -filters option to the add command so that an alternate include/exclude pattern file can be used. Currently you’ll need to create a new repository on a different location and then use the -repository option to specify the source directory. Or if that file is under a subdirectory you can just create a new repository under that subdirectory.
