One option is to use the archive function of BackupPC to create a tar file of the latest backup for each machine on your external drive. This is fairly simple to do and does not require BackupPC to restore files if you ever need to use it. However, this will duplicate all the files that BackupPC has pooled together, so it will require more space on the external disk that the actual pool directory uses. If you have lots of machines, then creating tar archives of them may not be practical and you may want to just copy the entire BackupPC pool. You can do this with Rsync for small installations, but as the pool grows it quickly becomes impractical due to the large number of hard links it has to deal with. Rsync will start either running out of memory or just taking way too long to finish. What I do is use a software raid 1 with three disks. Two of the disks are internal and provide redundancy for the server. The third disk is external and is removed and replaced on a regular basis to give me an off-site backup. -- Bowie ------------------------------------------------------------------------------ _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
