What I did here is not the second drive with the changer at all -- I change that tape by hand twice a week, and use it to generate an archival level-0 backup (stored in the tape safe) for long-term storage. I can use the tapes in the changer (on drive 1) to restore any file system to any day in the previous 20 days (since I have a 20-slot changer) and then can restore to one-week granularity for any week in our tape safe (which goes back two years).
I know it's not using both tape drives WITH the changer exactly, but it works well for our needs. -Ed > -----Original Message----- > From: Mark Lin [mailto:[EMAIL PROTECTED]] > Sent: 27 February, 2002 08:02 > To: Eric Trager; [EMAIL PROTECTED] > Subject: Re: Resolved - Multi-tape question > > > Perhaps add another configuration, use the second drive as > your tapedev > parameter and change the first and last slot number in your > changer conf > file.
