Thomas Mueller resolved JCR-1722.

    Resolution: Won't Fix

I agree, the garbage collection should not be run while creating the backup.

>            Priority: Minor
> During a backup, objects in the data store must not be modified or deleted. Otherwise
the backup is consistent.
> Objects in the data store are never modified. The only problem is if objects are deleted
while the backup is running. The data store garbage collection is the only place where objects
are deleted.
> There should be a way for a backup tool to 'flag' the data store (file data store and
database data store) to not delete entries. For the file data store, this could be done by
placing a specially named file in the root folder. For the database data store a specially
named entry could be used. Another idea is to use an in-memory state only, however this solution
doesn't work if multiple repositories share the same data store.
> To support shared data stores, the specially named file name / object name should consist
of a fixed part (for example the prefix 'stopdelete') and a unique id (for example a UUID).
