Default rdiff-backup question

Hi everyone,

i have installed rdiff successfully. now my question is, if someone deletes files from the server the backup is taken, will this files also be deleted on the backupserver or will they still be there. how can i remove them?

Have a look here: http://www.nongnu.org/rdiff-backup/features.html

Keeps increments: Normally, with a mirror, any changes made to the source directory are immediately sent to the backup directory, and old changes are lost. rdiff-backup saves those changes in the form of reverse diffs, so you can recover the older form of the file.

For instance, suppose last week you deleted half of some document, thinking that what you had written was garbage. Yesterday, your backup event ran, saving these changes. Today you realize that you were on to something and want what you deleted back. If you just mirrored, you would be out of luck, since the copy on your mirror would be the newer one. With rdiff-backup, the newer version would indeed be present, but in a special directory (rdiff-backup-data/) there would be a file that recorded this change. Running rdiff-backup on this file recovers the version from a week ago.
