You'd probably be better off writing a CMS client (otherwise you lose the file-level capabilities of Amanda) for Amanda, or porting the Bacula file daemon. The problem with both Amanda and Bacula is that they don't really take into account the structured properties of the file (RECFM, LRECL, etc), or that filesystems are not presented as a single tree on a client, so we'd have to figure out a way to do that. That's not too hard for SFS or BFS, but minidisks are a challenge to that model. That said, since DDR is a CMS application, you'd have to drive a CMS machine to do it (DDR is a application, not a CP command, so it can't coexist with a running Linux). You could use CMSDDR (does the same thing as regular DDR, but produces a CMS file which can be written to a NFS host using the CMS NFS client, and then backed up with Amanda or Bacula). Obviously, there needs to be enough disk space on the Unix box to support that much data (CMSDDR doesn't do a lot of compression), but since a 3390-3 is only a few gig per volume, that's not an impossible thing in these days of cheap 300G SCSI disks. I have a mostly working CMS Amanda client written in Rexx and Pipes. I haven't put a lot of work into it in a long while because Bacula looks a lot more promising, but if someone is really intersted, let's talk offline on what needs to be done. I'd really like to focus on Bacula if possible; it's a lot more sophisticated. -- db ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
