In our Apollo Network (SR 9.7), we have the following:

12 DN4000          with 150MB Harddrives
2  DN3000          with 330MB Harddrives
2  Storage Modules with 280MB Harddrives
10 Diskless DN300's and DN320's
2  DSP80's
1  DSP90

Total Disk Space: 3 GB
======================

    In order to to do a full backup, we use a Cipher
tape drive with 30MB Magtapes.  We find this process
slow (1 hour per tape) and error prone. (I/O errors mostly)
===========================================================

    We need to find new strategies for backing up
user files.  If you use:

              1) High density tape drives
              2) Tape cartridges
              3) Optical Disks
              4) or anything else

for backups, and are satisfied with the results, please
outline:

     1) the type of equipment you use
     2) any interface requirements 
        (ie. only on DN4000's running SR. 10)
     3) the impact of SR. 10 (if applicable)
     4) speed and accuracy statistics (best guess)


Thank you for your assistance...
