It's different from backup and if it's in realtime it's very strong. Delete the file, oops, recover the file.

Indeed you first need to decompress the backup, show files belonging only to the user, when the user for example click on the file in the file list, show the different version available, etc ... A better approach should to use something like hdlist which contain list of backed up files + attributes ( atime, backup timestamp, size ) for each user/owner. So this apps browse in this db, show the files belongings to the owner, etc ... It may be interesting and think as an extension for drakbackup but : 1�/ it's very complicated to implement 2�/ I don't think it will be seen in 9.2 3�/ amanda/Arkiea may be best suits for this -- FACORAT Fabrice <[EMAIL PROTECTED]> Fiventis
