HI all,



I'm using RS6000 with AIX 4.1.4 with internal 8 mm tape drive
(/dev/rmt0). Currently a lengthy and complex CRONTAB script is taking
backup, but I found it non-reliable. But advantage is, it prompts for
second tape, if needed, and can take Incremental backup. So now I want
to try savevg:



Questions are :



1) Do I need any specific level of bos.sysmgt.sysbr fileset for savevg
to work properly?

2) Is there any work around to take incremental backup using savevg ?

3) Should I use -p option of savevg or not ?

4) What should be the block_size for tape drive to get faster backup?
(Current setting is 512)

5) In general, do you see any problem using savevg with AIX 4.1.4 ?



Your advice will be appreacited........

Thanks in advance
