cannot recover files

Lisa Dingman — Tue, 21 Oct 2008 12:45:46 GMT

Please help. I was cleaning up files and deleted files under /usr/share/lib because of the date and then found this has caused problems. In trying to restore from SAM never restores. In trying to restore from terminal using:
cd /usr/share/lib/tmp
frecover -x -oF -i /usr/share/lib

I get a message saying something to the effect of unable to find /dev/rmt/0M
How can I restore these files

Lisa, first things first, DO NOT ever remove files from an lib directory unless you KNOW for a fact that they are irrelevent. That being said, there AREN'T files that are irrelevent in a lib directory, they MUST remain.

How do you backup? Tape backups? Local drives? What software? Type of server...etc....

Hi Lisa:

The message is telling you that the default device from which to recover your files is '/dev/rmt/0m'. You need to mount your tape there or specify the appropriate device. For instance:

# frecover -x -oF -i /usr/share/lib -f /dev/rmt/1m

Regards!

I did use that exact statement, we backup using Sam to sam device /dev/rmt/0m

woops didn't see the 1m - my mistake will try

I tried:
frecover -x -oF -i /usr/share/lib -f /dev/rmt/1m

get message unable to find /dev/rmt/1m

Would being in /usr/share/lib/tmp have anythign to do with it? Users are on system so I hate to back up to /usr/share/lib right now - but '0m' or 1m' doesn't work

Lisa, can you print the output from ioscan -fnC tape?

I have been doing at the terminal. So I tried in terminal mode in SAM - am getting blinking curser so far no 'unable ' message would that mean is restoring. When I do an auto restore using SAM interface, just gives me "restoring...." forever, am wondering if it is doing the same. I as you can see am rather green to sys admin, we are getting new server and my director wanted old files cleaned up, guess this was not a good idea.

Yes, it is:

It looks like nothing is still happening -

# cd /usr/share/lib/tmp
# frecover -x -oF -i /usr/share/lib -f /dev/rmt/0m

just a blinking curser for the past 15 minutes - yesterday let it run an hour and nothing - any other suggestions please?

Adam W. — Tue, 21 Oct 2008 13:23:54 GMT

Lisa,
I would say give it some time to run. I ahve had a few backups take HOURS. I am not sure why, but they were successful.

Re: cannot recover files

Lisa Dingman — Tue, 21 Oct 2008 13:25:26 GMT

Thank you Adam, usually a complete backup takes 2 1/2 hours that was why I was wondering, I will let it run to see what happens, would you infer that it is recovering then?

Re: cannot recover files

Lisa Dingman — Tue, 21 Oct 2008 13:28:17 GMT

I am not sure how this relates exactly but since term and terminfo gone wasn't sure if the command to frecover from SAM terminal could get through. When I tried at the console would get the error message about not finding /dev/rmt...

Lisa,

Take a look at your tape drive. Is the "tape in use" light blinking? If so, that's a pretty good indication that it is, indeed, doing something.

Is there a way to see if files are copied by any chance while they are in process, if I look at directory copying to is empty, is this to be expected by any chance. In Windows you can see what files are copied, not sure if is relatable.

Adam W. — Tue, 21 Oct 2008 13:35:44 GMT

Hard to say whether or not it is recovering at this point. I would be patient for now and give it some time. For fuuture refence though, I wouldn't remove ANYTHING simply based upon the date of the files. Some system files NEVER change so they LOOK like they have never been used, but I can assure you they are being utilized. Best practice is basicall if you are not positive on what it is or what role the file plays on your system, leave it alone, ya know.

Lisa Dingman — Tue, 21 Oct 2008 13:37:00 GMT

Yes Pete, tape in use is blinking. I have to say learning by the seat of your pants isn't all that enjoyable.

The *easiest* thing to do would be to go look at the tape drive - the light should be flashing away if its doing something...
