David, First,I would read the paper disaster recovery. Second,I would ask the question why can you not do full (normal) backups every day unless of course your data outstrips your tape size on each server. I think you are reading into differentials too deeply. Personally I would recommend Veritas Backupexec as NTBackup is a stripped down version albeit free, but again it comes down to the horses for courses and each person can tell a different story where backups are concerned. My reasoning is the restore times from testing are faster with Veritas. Whether you want to pay that much more is the question?.
Yours sincerely, Sean McGilligan [ I realize there are no stupid questions but only stupid people who ask questions so I'll throw my hat into the stupid ring as this is probably very simple... I finally got my boss to buy a DLT drive exclusively for each of my Exchange 2000 servers. From all I've read here and elsewhere I decided to use NTBackup rather than ARCServe on my servers. I cannot, however, find a way to setup the backups correctly. I aim to do a nightly full backup at 11pm with differentials every two hours from 6am until 8pm when the tape would be replaced for that night's backup. I see in the backup wizard how to set the daily backup as a "normal" and how to schedule a second "differential" backup for only the information store at my selected times. However, the option to "append" rather than overwrite the media is grayed out on the differential. If this differential is going to overwrite the full backup then a single tape source for backup isn't feasible. I'm sure it is but I'm just missing something so anything you can offer would be appreciated. ] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
