Hello list,
I have a situation here and I am not sure how to go about doing this
right. I am sorry for the length of this e-mail. I am so new to
amanda, I really did not know what would be useful information, so I put
together everything I thought might be usefull. I am sure that this
would be trivial for anyone with some experiance using amanda. (Thats
just unfortunely not me) :)
I have a backup that was done using amanda on a 35gig DLT tape. I am
tring to recover some files from the tape. I thought that I would not
need to use amanda todo it, I could just get the info I needed from tar,
but everything I have tried has failed, so now I am thinking maybe using
amanda is the only way. I will list out what I have tried and what my
results were hoping someone can point me in the right direction as to
how I can get to those files. :)
I tried simply doing a:
tar -xvf /dev/st0 -b 128
After MANY hours, it ended with:
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
But I did get two directories:
indexes
spool
My indexes directory listing looks like this:
20020318
20020319
20020320
20020321
20020322
20020329
20020330
20020401
20020402
20020403
And I know (from the label on the tape) there was a full backup done on
Mar 30 (20020330). When I dig down into the index directory, I can find
the idx file with the files I need:
indexes/20020330/fileserv/FILESERV_200203300505_export_home.idx
So I look in the spool directory and figure out the last file that was
extracted was from the day before 20020329.
Thinking something went wrong along the way, I did:
dd if=/dev/st0 of=fileserv.tar bs=64k
I end up with a 5 gig tar file. When I try to extarct the file I need I
get the same EOF error.
So I am assuming when you do a full backup with amanda, it does
something different. I installed amanda and tried using amrestore and
am recover, but to no avail. I cannot get the syntax correct to get
them to do anything.
When I view the contents of the tar, it is in this format:
-rw-r--r-- backup/backup 14852500 2002-03-18 03:35:16
spool/20020318/fileserv/FILESERV_200203180324_export_home.tgz
SO I think the backup/backup has something todo with hostname. The
something I need to get this to work with amrestore I think.
Can anyone point me in the right direction? Does the EOF mean the
backup is no good? Or do I need to use amrestore or amrecover to get to
the files I need? If I do, what would be the most logical syntax to get
to those files?
Thank you very much just for reading this far. :)
Jimmy
