Speaking from my experience, I would risk to say that a ~2 TB RAID-5 array of five SATA disks would be a maximum, anything bigger than that would go to a crawl with BackupPC heavy hardlinking. So when asked: "is backuppc up to the task of backing up TBs of data"? My answer would be: yes. Right now, I have ~14 TB of data in BackupPC's archive, and it all fits on a 1.2 TB filesystem (~65% full) - that all sits on a 5x SATA RAID-5 array. But I feel I'm hitting the limits of that setup. In other words, for a filesystem bigger than 2 TB for use with BackupPC, don't use RAID-5 (but RAID-10, for example), use faster drives etc. Of course, your mileage will vary, will depend on many other factors. -- Tomasz Chmielewski http://wpkg.org ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
