Re: Interrupted backups

You're correct that you restart the same way as the initial command.

If the resulting file ends in .part, it is incomplete; if the file has the full name you specified for it without the .part, it is complete. (Standard advice to check by restoring from it applies. :)

Hi Marc,

Thanks for your reply and apologies for not noticing that bit in the manual. So if I've understood it properly, the answer is yes, Tarsnap can re-start a partial archive. I guess the command to re-start would be exactly the same as the initial command. Would that be a fair assumption?

If this isn't a completely thick question, how would I know the archive was now whole and complete? That is, no data missing or lost?

Regards,

John

Can anyone advise on the following please?

In the event that a backup gets interrupted - either by technical problems or because it's taking so long and I want to switch off my computer - is Tarsnap able to pick up where it left off once the connection is re-established? Or would I have to start the backup all over again?

What would be the command for re-starting an interrupted backup?

Thanks for any advice on this matter.

Best wishes,

John Gamble
