Using DD to restore suse 9 image on a suse 8 box
Hello,
We are trying to find a easy way to upgrade our old suse 8 boxes to Suse 9. I have discovered the the DD command that looks to be a way to restore a image from Suse 9 to a box at our other locations.

Question, could I use the DD command to restore a image I backed up from a Suse 9 box onto a Suse 8 box. Both systems will have the same exact harddrive and partition information. And for my testing purposes can I also go the other way. So if I successfully put the suse 9 image on my test suse 8 box, and I restore the suse 8 image back.
Also on the restore from tape would I just do
Code:
gzip -dc /dev/ht0/image.gz | of=/dev/hd0

assuming my tape is ht0 and my partition is hd0.

Only issues I see is that I would need to somehow backup the system network, printer settings and such which maybe a problem with this method and restore them afterwards. Trying to find a method that will have the least involvement possible at the remote locations.

Thanks for any help on this...

SuSE 11.4 Filesystem Backup and Restore

Hi, The dump and restore commands are missing from this server under SuSE 11.4 for unknown reasons. What is the cleanest way to backup and restore filesystems? Clean means to keep all the original hard/soft links and timestamps. Is find/cpio clean enough? $ cd /source $ find . -print | cpio... (4 Replies)

xfs_mdrestore(8)					      System Manager's Manual						  xfs_mdrestore(8)

NAME

       xfs_mdrestore - restores an XFS metadump image to a filesystem image

SYNOPSIS

       xfs_mdrestore [ -g ] source target

DESCRIPTION

       xfs_mdrestore  is  a debugging tool that restores a metadata image generated by xfs_metadump(8) to a filesystem. The source argument speci-
       fies the location of the metadump image and the target argument specifies the destination for the filsystem image.  If  the  source  is	-,
       then the metadata image is read from stdin. This allows the output of be another program such as a compression application to be redirected
       to xfs_mdrestore.  The target can be either a file or a device.

       xfs_mdrestore should not be used to restore metadata onto an existing filesystem unless you  are  completely  certain  the  target  can	be
       destroyed.

OPTIONS

       -g     Shows restore progress on stdout.

DIAGNOSTICS

       xfs_mdrestore returns an exit code of 0 if all the metadata is successfully restored or 1 if an error occurs.
