I haven't tried the syntax but it will be something like this. machineA - system to be backed up machineB - system with tape unit from machineA sudo tar cf - /home | ssh adminuser@machineB dd of=/dev/nrsa0 the '-' on the tar command makes the 'f' go to stdout. pipe into ssh and on remote machine dd takes stdin and send out using 'of' to /dev/rnsa0 or whatever your tape device is named. > > > regards > > simon > > Krishnaprasad_K@xxxxxxxx wrote: > Hi, > > Have you tried taking backup using tar utility instead of rdump. > If you take backup and try restore using tar, you may face issues. > > So try to take backup and restore using tar utility. > > tar -zcvf /dev/rmt/0hbn will do backup and > tar -zxvf /dev/rmt/0hbn will do a retrieve operation. > > Also you can verify the content of tape after backup using > > tar -tzf /dev/rmt/0hbn - it will list the contents of tape. > > Note :- Make sure that you have rewinded the tape before trying to > restore. > > There are other utilities available for tape backup for eg/- cpio > > Regards, > Krishnaprasad > -----Original Message----- > From: redhat-list-bounces@xxxxxxxxxx > [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of sylvan dacounha > Sent: Tuesday, June 12, 2007 3:47 PM > To: General Red Hat Linux discussion list > Subject: problem with restore > > Dear ALL; > > I am using REDHAT 9 server and doin a back up on remote tape but the > restore gives prblem > > > let me expalin > > > I have a redhad 9 server and my tape drive is on a SUN Solaris server. > iam backing up the redhat 9 server on the tape drive attached to the > SUN machine > thats doin a remote backup > > the tape is dds3 type. > > i use the command from the linux machine to backup on tape attached to > SUn server > > rdump 0f xx.xx.xx.02:/dev/rmt/0hbn / > > and it backs up succesfully witout any errors > > but i want to restore now > so from the linux machine i use the command > > restore -if xx.xx.xx.02:/dev/rmt/0hbn > > but it gives me a error message > > Connection to xx.xx.xx.02 established. ----- where xx.xx.xx.02is the > SUN server IP > restore: Tape is not a dump tape > > if i use tar command > > tar -tvf xx.xx.xx.02:/dev/rmt/0hbn it says > > tar: This does not look like a tar archive > tar: Skipping to next header > tar: Error exit delayed from previous errors > > > now if i go to the SUN sparc machine and run tar command > > tar -tvf /dev/rmt/0hbn > > it says > tar: directory checksum error > > > if i run ufsrestore > > ufsrestore -ivh /dev/rmt/0hbn > > its says > > Verify volume and initialize maps > Media block size is 20 > Volume is not in dump format > > how can i test my restore .. or which command can i run with swiches > for a sucessful restore > > > also how can i list the contents of tape > > > thanks and Regards > > > simon > > > > > > > > --------------------------------- > The fish are biting. > Get more visitors on your site using Yahoo!
