UNKNOWN_FAILURE error with online backup

Hello,

I too have the “unknown” error as other people!
Local backups are working fine, today I activated the online one, started the first one and got this:
==============================================================
8th juil 2014 4.08.38 Error The activity failed: The server failed to retrieve the backup. The reason is unknown. Please consult the activity log.
8th juil 2014 4.08.38 Error The server failed to retrieve the backup. The reason is unknown.
The unknown error token the server returned was: UNKNOWN_FAILURE
8th juil 2014 4.07.49 Information The backup is 16.9 MiB in size. Starting transmission to the online vault.
8th juil 2014 4.07.49 Information Deleted files processing completed.
8th juil 2014 4.07.49 Information File collection completed.

So what’s wrong?

Is it possible to set the time with the local timezone instead of the Online Backup server one?

Thank you.
