[Networker] Networker 7.3 client/server on RHEL 4 - recovery problem
2006-06-19 20:13:01
Greets.
I'm looking for another installed environment, that like mine, has
Networker 7.3 (or later) on RHEL 4 for both the server and the client.
If you have such a beast, could you please test the following for me?
I've seen the problem below on both 7.3 stock and 7.3.1 stock.
PROBLEM: Files that are recovered are not the same as the files that are
masked for recovery while doing a browse recover.
RECREATE:
1) On the client run "recover -d /var/tmp/recover"
2) In the recover shell, run "add /etc" (do not directly select
individual files or do "cd /etc; add *")
3) In the recover shell, run "recover" (Do not do any file selection
commands between steps 2 and 3)
4) Look for files recovered into /var/tmp/recover that do not match what
is the expected current file according to the existing files in /etc/ or
the Networker index.
For example, on several systems I see the following with files that have
recently changed:
File in Networker index:
2222 Jun 14 22:42 /etc/passwd
File actually recovered:
2054 Jun 1 18:05 /var/tmp/recover/etc/passwd
I think this is tied to having multiple incremental backups after a at
least one full backup. If the files recovered haven't been changed since
the last full I think everything will be great. If on the other hand,
multiple versions of the file exist in the Networker index then possibly
the wrong file will be restored.
I appreciate anyone who can confirm they also see this problem. It's
driving me batty :) To confirm the some possible FAQs, I've been through
my indexes with nsrck and also _can_ recover the correct file if I
directly select the individual file in the recover shell. (eg: "cd /etc;
add passwd; recover;") Also, saveset recovery appears to have no issue
either. Basically the two methods confirm for me that the file is in
fact on the tape and can be read successfully depending on how it is
selected for recovery.
Odd, eh? I discovered this little issue when attempting to do a bare
metal recovery one nice. The system started to run through init and
ended up oopsing due to all sorts of odd library combinations!
Thanks for any help!
