For Windows systems, BackupPC doesn't back up ACLs, alternate data streams, hidden or system flags, and so on, so, aside from relatively straightforward permissions, you'll either need to add your own or skip it. > When restoring data to a NTFS filesystem I've encountered permission > issues which either > a) prevented the user from accessing his/her data > b) the restore process seemed to have locked itself from writing down > the tree by changing permissions of a parent folder so that it couldn't > write anything below that folder Generally speaking, I back up the files via rsync, then use .zip files for partial recoveries, and tar for bare meta recoveries. It's possible to pass the right flags to rsync so that you can recover that way as well, I just haven't found it worth bothering. > Those weren't critical issues since I could still get at the data in the > end, but it was far from ideal. > > To note is that on both of the above the underlying OS was reinstalled > from scratch, so I'm suspecting that user ID mismatch might be the > reason, but I've failed to confirm that. cygwin uid/gids get mapped to SIDs in Windows ... but I don't know a way to reconstruct a SID from a uid/gid.

I'd recommend rsync+vshadow to get all the files, of course -- for a bare metal restore, if you don't recover the registry, you won't have anything to map to, anyway, so I'm assuming you're going to do that as well, in which case, what you lack is a back up of your ACLs (possibly: all that other stuff, I don't know how important any of that is to you.) ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
