For .bvfs_update, it is an incremental process. I mean that there is possible to add all jobids at once or all jobids separately. Both ways are valid. For example if you have: Full jobid: 1 Incremental jobid: 2 Incremental jobid: 3 There is possible to run: .bvfs_update jobid=1,2,3 that is the same as running: .bvfs_update jobid=1 .bvfs_update jobid=2 .bvfs_update jobid=3 and the last way can be used in the Runscript. In the Runscript can be used the following characters substitution: https://www.bacula.org/15.0.x-manuals/en/main/Configuring_Director.html#blb:character_substitution so %i is ideal for that because it is replaced into JobId. Normally this Runscript could look like this: Runscript { Runs When = After Runs On Client = no Console = ".bvfs_update jobid = %i" } BUT there was a bug in Bacula that caused it didn't work. It is here: https://gitlab.bacula.org/bacula-community-edition/bacula-community/-/issues/2419 I don't know if it has already been fixed. Also worth to mention is that some Bconsole commands are not supported to run in Runscript Console directive, however .bvfs_update is marked in code as supported. For the Runscript and .bvfs_update if this bug still exists, you can put executing .bvfs_update in a script and use Runscript Command directive like this: Runscript { Runs When = After Runs On Client = no Command = "your_script.sh %i" } Best regards, Marcin Haba (gani) -- "Greater love hath no man than this, that a man lay down his life for his friends."
