Some numbers from another site, with hardware specifics.
My experience of late is that a db backup of 5737933 pages takes about 15 minutes, AIX 5.2, p650, 3590E drives, SCSI, with disks on modern SSA, RAID 1+0 (mirroring and striping), raw logical volumes. Restoral takes about an hour. I would imagine that the restoral would take longer if the db volumes were JFS, given sync processing. In ADSM 3.1 on an R3U AIX 4.1 system, mostly JFS volumes on older SCSI, same 3590E drives, the backup used to take 1.5 hours.
