Question: Old Irix tape backup. Recovery on Linux (xfsdump/xfsrestore)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Anthony here,

I'm not sure if this is the correct place to send a question, If I am wrong I would appreciate if you could send me in the right direction.  I have come across the oss.sgi forums a lot looking for a solution to my problem but I could not find much. 


Here's my situation.

I have a bunch a tapes that were created way back when using an IRIX system. Some kind of version 6, perhaps even the latest version. anyway I am able to peak at the headers to determind the the file type on the drive is indeed:

xFSdump0....   or when I make a sample using 'dd if=/dev/nst0 of=./test.img' '+ 'file test.img' I get XFSDUMP archive (version 2)

So, instinctively to get the data off the tapes I would think would be as simple as:

sudo xfsrestore -f /dev/nst0 ./path to where I want it stored

Then I get: 

using dump format 3

xfsrestore: searching media for dump

xfsrestore: preparing drive

xfsrestore: examining media file 1

...

xfsrestore examining media file xx

the following dump has been found on drive 0:

hostname: isp---------(stuff)

mount point: /isp-iga

volume: /dev/rdsk/sks0d2s7

session time: Mon Jan 10 11:47:42 2005

media label: "backup"

file system id: xxx....

session id: xxx...

media id:...

restore this dump?

1: skip

2: restore (default)

> 2 (enter)


====== 

examining media file 0

reading directories

examining media file 1

reading directories

... and so on

no files selected for restoral



====

1: media change declined (timeout 3600 seconds)

2: display media inventory status

3: list needed media objects

4: change media (default) 


3 and 4 do nothing

I get no media needed. and If I press 4 same menu comes back. 

2: media file xxx (xxx) where xxx is a number

used for directory restoral 

first extent contained: ino xxxxxxxxxxxx off 0

next extent to restore: ino (same as above) off 0



and If I click 1:

restoral interrupted use -R

restore summery:

stream 0: /dev/nst0 quit media no longer usable

restore status: QUIT


Then if I got to the directory where I pointed all I have is:

orphanage/ 

xfsrestorehelperblahblah/   

where orphangae is empty and the other contains like 5 files that are just something else. 

What am I doing wrong here ?? any help would be great.

Thanks
