We use ufsdump to backup our file systems to 8 mm, 4mm or DAT 72 tape drives. The default blocking factor ufsdump uses is 64 (without b or c option) and the problem with this is the amount of data that can fit on a tape because of the IRG.
My questions are: - how can I find out the optimum blocking factor (or that is supported) for each tape device (8mm/4mm/DAT72)? - what are the issues of changing the blocking factor to 512 (ufsdump code seems to cap the blocking factor to 512)? Thanks in advance. -- prasad This message posted from opensolaris.org _______________________________________________ ufs-discuss mailing list [email protected]
