When restoring from a savepoint the following error is observed in the failed job log:
"Error Message: Repository content is missing or corrupted"
If a savepoint is visible in the repository through Windows Explorer that does not correspond with an entry in the 'My Repository' view in vRanger, then a Restore from Savepoint Manifest will be needed to restore this savepoint.
However, if the savepoint is put back into its original location, then restore from savepoint will work as expected.
