[Dump-users] Does restore purge extraneous files (orphans)?

[Keith G. Robertson-T. <dum...@ge...>]

Hello Stelian and anyone else reading.

I hope the dictum "there's no such thing as a stupid question" is well
accepted on this list, because this may be the mother of all stupid
questions. Err..

It's not absolutely clear from the manual, but does restore purge files
that were deleted between incremental dumps?

E.g. If file foo.bar exists, then I do a level 0 dump, then I delete
foo.bar, then I do a level 1 dump ... if I then wipe the filesystem and
restore the level 0 dump then the level 1 dump in sequence, will foo.bar
be removed (like "rsync --delete")?

The only info I could find was here:

http://www.searchstorage.com.au/topics/article.asp?DocID=1267195

The info there suggests that dump stores a map of inodes deleted since
the last dump in an array called "usedinomap". Does restore actually use
that info when restoring incremental dumps, and if so - does it only do
that if the "r" switch is used, as opposed to "x"?

TIA.

PS: dump is still the best backup program, even after all these years.
Amazing, isn't it? [waves to Linus].
