Currently I am just running daily backups to tape. The following things I am considering, and would like input from the rest of you. 1) Disk Mirrorring or Disk Duplexing w/daily tape backups 2) A disk array for each server running RAID 5. Daily tape backups. 3) Duplexed RAID 5. Daily tape backups 4) A central storage unit for all the servers running RAID 5. What have you found to be the most cost effective way of *resonably* maintaining uniterrupted disk access? My total data storage needs (NOT including the 18Gig Newserver) is around 10Gig, but it will probably be around 30Gig within a year. Thanks for your input! Mury GoldenGate Internet Services.
