I know its disconcerting, but this zLinux is only being used as a basis to start of a POC idea.
Ill look into both DDR and TSM then :) B -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Scott Rohling Sent: 17 July 2008 16:42 To: [email protected] Subject: Re: New to zLinux... Backup solutions... A bit disconcerting that a backup was taken but the restore process isn't known. At the simplest level, you can DDR the DASD for VM/Linux to tape or DASD.. then use DDR to restore it. For Linux - the guest should be logged off if you want to ensure the backup will result in a working system when restored. A better solution might be to use a TSM client on your Linux guest to backup the Linux filesystem at the file level. DDR is only going to provide you with physical copies, so restoring a single file that Linux needs will require you to restore the disks making up the filesystem, mount them, and pull of the files you need. As far as whether it needs to be restored to the same disks -- no - with z/VM you can restore to other disks and then alter the directory entry for the Linux guest to point to that DASD, using the same virtual addresses. Be aware that you need need to use the same disk 'addresses' unless you're going to modify modprobe.conf (RH) or zipl.conf (SuSE) to include those address ranges.
