BackupMainService failing tests

[joaomoreno]

These tests often fail with timeouts. Not sure whether IO is really slow, or if there's really something wrong with the test never completing.

Lets first increase the timeout and monitor the test further. I see only sync execution in that test so I would expect any error to bubble up properly to the console.
