It is worth noting that even Red Hat, long the champion of ext*, has officially abandoned it and will do no further development on it. (And frankly, it didn't come a day too soon.) I haven't run an ext* filesystem in years; every Unix filesystem I have is either XFS or ZFS. > - How can I know the amount of IOPS needed for my local disk? > - What does Bacula need most: high IOPS or throughput (MB/s)? Well, to a certain extent it's the same thing, at the storage level. But consider that you are going to be doing mostly long streaming reads and writes (a use case which the design of XFS was specifically optimized for when SGI developed it). That said, for Bacula storage purposes, what you care about is throughput and stability above pure IOPS. > - Is it worth using RAID1 or RAID10 for improving performance? On AWS it's all RAID under the hood anyway. RAIDing virtual RAIDs probably doesn't gain you much. That said, in the database and backup world it's generally considered that RAID10 is best for performance. -- Phil Stracchino Babylon Communications [email protected] [email protected] Landline: +1.603.293.8485 Mobile: +1.603.998.6958 _______________________________________________ Bacula-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/bacula-users
