Kopano-backup error when backup-target full

  • Hi guys,
    as mentioned in the topic: when it occurs that there is no free space on the target storage - backup failes of course. However, after freeing some space it does not resume. Following errors appear

    2020-06-24 23:02:18,645 - backup0 - ERROR - Traceback (most recent call last):

        self.db[key] = value
    bsddb3.db.DBPageNotFoundError: (-30986, 'BDB0075 DB_PAGE_NOTFOUND: Requested page not found') 

    My only solution is to delete the contents of the backup folder and restart the backup. Is there any another possibility?

    Hi @KaBi,

    the actual backup data is stored in Berkeley DB files, which probably were corrupted when your disk ran out of space. Berkeleydb is a well used technique and there are external tools to inspect and repair these files.
