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

Nope, savevg is a link to mksysb, at least is on later versions of
AIX. Issue "ls -l $(whence savevg)" to see if it is the case on 4.1.4

Yes, use a different backup tool. savevg backs up ALL files in the
specified volume group except those specified in /etc/exclude.<volume
group>

The -p option is only valid in 4.2 or later versions of AIX

Experiment and see what works best with your tape drive.

Yes, it's unsupported, in fact, the last version of AIX (4.3.3) goes
out of support shortly. But apart from that, no.
