re several circumstances that might cause the end user to wish to manipulate archive or metadata contents. It would be good if there were a programmatical way to do this instead of mucking with it by hand.

Examples are:

  • sync metadata to archive content

' useful when archive content has been inadvertantly destroyed.

  • delete file(s) from the archive

' useful for space management, and also perhaps some forms of archive corruption. ' ideally syntax would allow for removal of either older versions of target, leaving newer ones, or removal of newer versions, leaving older. ' in particular, removal of most recent version might be useful for corruption, while either newest or oldest might be good for space management. syntax could ideally be fundamentally similar to --remove-older-than.

Usually on bigger backup systems you can set retain policies on certain files so that they will be saved forever, while other files will only be saved for 3 months.
