It's more complicated than that, because the header of a file-in-holdingdisk is different than that from a file on (v)tape. Moreover, holdingdisk files could be chunked, while (v)tape images are not.

Keeping backups on holding disk after writing to tape
Hi all, i want the backed up files from a nightly amdump-run to remain on the holding disk (after they were successfully written to tape!) at least for one day. So it would be possible to do faster and more comfortable restores the next day. Is there an option to acomplish that? And if there is one, is it possible to force amanda to remove that data after a defined period of time? Many thanks in advance and best regards, Christoph

Many thanks in advance and best regards, Not that I know the answer, but when I think about it I totally agree with this being a great function. I would immediatly configure my system to leave the last nights backups on disk until the next job starts, then it could purge yesterdays data if it was successfully written to tape. /Andreas
Re: Keeping backups on holding disk after writing to tape
It sounds like a good feature - if you have enough holding area you could even hold files for a configurable number of days. You'll need a way to differentiate held files from ones that didn't properly flush though, perhaps moving to a subdirectory of the holding area, MMDD-HELD or modifying the file name somehow.

Many thanks in advance and best regards, I don't know if anyone has ever tried a combination of real and virtual tapes in a RAIT mirror config. One drive could be your tape, the other could be a disk-based one. I've always felt this could be an interesting solution to lots of arrangements. Off-site tapes for archive, on-site vtapes for fast and easy restore. -- Jon H.
