How do I determine what tape blocksize my Hidro backups are using? I am writing to IBM 3592 E05 units in a 3494 tape library.
HiDRO blocks its records at 65280 so the blocksize for all backups is 65280, regardless of what tape media you are writing to. Similarly, VM:Backup creates a blksize of 65535.
So, basically, both are 64K records in length.
