System Disk recovery - UNKNOWN file. amrecover: Cant read file header Hi I am having other problems now where I have attempted to use vxrestore and restored back most of the system. However, there appear to be some files missing so I am having to use amrecover to restore certain directories in /usr/local on my HPUX machine I am using my July full backup tape which was successful but amrecover keeps me for the last full backup tape (Fri3.1) which is a corrupt tape. Also I have noticed that when I load the July tape and set it to the correct directory to restore, on the client when I do a listing of whats on the July tape, its giving me the date of last Friday (Fri3.1) WHY? It should be giving me the date of the July full backup. How can I force amrecover to read off the correct tape and not ask me to load Fri3.1 $ amadmin Weekly find telhp6 /usrWarning: no log files found for tape Fri4.1 written 2004-04-23Warning: no log files found for tape Mar0.1 written 2004-03-28Warning: no log files found for tape Weekly5 written 2004-02-28Warning: no log files found for tape Weekly4 written 2004-02-14Warning: no log files found for tape Weekly3 written 2004-02-07Warning: no log files found for tape Weekly2 written 2004-01-30Warning: no log files found for tape Weekly1 written 2004-01-23Scanning /amanda...Scanning /amanda1... date host disk lv tape or file file status2004-06-25 telhp6 /usr 0 Jun0.1 95 OK2004-07-23 telhp6 /usr 0 Fri4.2 75 OK2004-08-03 telhp6 /usr 0 Jul0.1 84 OK2004-08-06 telhp6 /usr 0 Fri1.1 109 OK2004-08-13 telhp6 /usr 0 Fri2.1 100 OK2004-08-20 telhp6 /usr 0 Fri3.1 87 OK Here I load Jul0.1 and fsf to 84 Then I go to my client: # /opt/amanda/sbin/amrecover -C Weekly -t tsssun1 -s tsssun1AMRECOVER Version 2.4.4p2.

I realised that I had commented out the WEEKLY/disklist (being over
cautius last night) so thats why there was no dump to list. When I do it
now - it works ok:
Fine.
Was this backup made by dump, then you need restore, but if it was
created by gnutar than then you gnutar to restore.
Looks like it was done by dump. Below is a cut of the WEEKLY/disklist
file for telhp6 and the WEEKLY/amanda.conf file.
DISKLIST
...
telhp6 /opt always-full
...
define dumptype always-full {
global
comment Full dump of this filesystem always
compress none
index
priority high
dumpcycle 0
Unless dumptype global does not contains program GNUTAR, then
it is indeed dump.
You can also verify this on the amanda tape header, which contains
this information too!
mt -f /dev/rmt/1ubn rewind
mt -f /dev/rmt/1ubn fsf 4
dd bs=32k count=1 if=+dev+rmt/1ubn
and voila; you should see something like:
AMANDA: FILE 20040623 host /the/dir lev 0 comp N program /usr/bin/gtar
To restore, position tape at start of file and run:
dd if=tape bs=32k skip=1 | /usr/bin/gtar -f... -
But I guess you'll see restore instead of gtar.
Or do you see a variant of restore, like vxrestore? See below.
When trying the amrestore its still complaining about Tape is not a
dump tape
First you need to be sure about which program is generating that error
message.
I guess it is the restore command.
Try doing a strings -a /usr/sbin/restore and verify if there is
message Tape is not a dump tape.
How do I use GNUTAR (please plase give me an example using hostname:
telhp6, partition: opt, amanda server: tsssun1
(although I dont think its using GNUTAR from the info above)
as root:
cd /the/destination/folder
remsh ...amrestore-cmd-as-used-is-ok... | tar -xpvf -
But I believe you are correct in using restore.
Are you using the restore on the correct architecture?
You need restore from the HP-machine for HP-dumps, and if
the filesystem was a special format like veritas, you need
the corresponding restore for that filesystem.
The amanda tapeheader for that backup does contain that information!
Instead of reading the slow tape over and over again, you can
dump the backup image on a disk (leave out the -p from amrestore).
And then try to find out what kind of image it is, with e.g.
using file telhp6._opt.20040824.0, and trying tar and/or
restore to generate a table of contents.
Just ignore the users (temporarily)
I do that anyway ;-)
Its my boss I'm more worried about !
Never mind about him, especially in these cases. (And he should know
that too!)
