after some time, every archiv gets broken, if we create another job (same) it works for a limited amount of time.
We get following error: (German)
It looks like the archive got corrupted when it reaches some specific size threshold and likely it is related to particular NAS device specifics where it cannot properly handle requests to large files. Possible solution would be to switch from "single-file" (always-incremental) archive format to "multiple-files" when you create a new backup task and specify the backup location (this option is available for new tasks only) - in this case all new incremental backups will be stored in separate files and thus the problem should be mitigated. If this doesn't help please contact our support team for assistance.
