Hello, I have few questions about my new backup configuration. Before asking my questions I will give you some useful information about what I need to do. I need a backup ± 10 servers with one full backup every week of 3,5 TB and an incremental backup of 100GB 5 times/week. I have 48 hours to do the full backup and about 8 hours to do the incremental backup. Every servers are on a 100Mb ethernet link. Considering all this parameters I need some advice about the choice of my hard disks. I'm planing to buy a StorageWorks array from Hp (DAS) but I don't know what's the best choice for the hard disks. I'm pretty sure that a fast hard disk is better for performance but it's not for money saving :), I'm wondering if big sata disks of 2TB/7.2k rpm are fast enough to achieve my backups in time or is it better to buy faster/sas disks to be sure it's done in time.
My second question is about an off-site backup solution. I will also buy another machine with the same configuration as the first one to do an off-site backup. What's the best solution to achieve this? A new backup of all my servers on the off-site backup server or a copy job from the first backup server to the second one? The off-site backup server will only keep the full backups not the incrementals and it's also on a 100Mb ethernet link. I hope you have enough informations to answer my questions. Thanks for your help. ------------------------------------------------------------------------------ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
