Retry on Input/Output error #190
Description
I’ve got an external drive with a very flaky USB-connector that likes to unmount itself when touched in the wrong way and then quickly remount.
Though when that happens attic check instantly crashes with an OSError and attic backup is starting to skip files.
I think it would be wise to retry for an amount of time in that case.
