DHCP and PCs
I am having problems keeping my windows clients backed up. Our setup is as follows: Mac G4 running Retrospect 4.3 We have 4 subnets in our building. Our G4 lives on one , while the clients live on the other 3 subnets. The problem appears to be related to DHCP. We have a seven day lease period for IP addresses. It appears that whenever the client's IP address changes, the backup server loses track of the client and therefore the client does not get backed up. I have to manually add them back into the client database and re-add them to the script. Does anyone have any experience or suggestions with running a backup server and using DHCP as the method for assigning IP addresses? Thanks Donny
Backup set comparison question....
I am suffering probably the perfect example of Murphy's law as it applies to backup - hard disk completely fails ( becomes invisible to the OS and all disk utilities) - one day before this, our APS HyperDAT Pro has failed, first chewing a tape, then ends up with another tape stuck permanently in the drive ( at least the drive was under warranty , by 10 days). - Trying to restore (using an overnighted replacement HyperDAT Pro drive) from the last good backup gives a -205 error, with a complete lock-up of RetroSpect and SCSI bus requiring a reboot, making me really popular with my users. - Assuming the -205 error + SCSI lockup indicates a SCSI issue ( since the replacement is SCSI LVD) I try various SCSI hoodoo measures ( new cable, new card etc), but finally discover that it is due to some kind of tape error. I still find this a bit perplexing that a bad tape can cause a complete and irrecoverable SCSI lockup. - So finally I was able to recover one complete backup from the backup set one earlier than the problematic one above. I can still recover some files from a newer backup set "as required", as long as I steer clear of the bad tape area. ( trial and error) My question is this... Is there any way in Retrospect to ask "Show me all the files in Backup Set A[006] (i.e.bad tapes) that are newer than the files in Backup Set B[004] (good tapes)", so I know what files are missing?

Re: Backup set comparison question....
You can determine what was on a bad tape by clicking on Configure - Backup Sets, selecting the Backup Set to which it belongs and marking the damaged tape "missing." Then go through the motions of a search and retrieval (Immediate - Restore - Search) and click on searching when you have selected the Backup Set and a destination drive. Make sure you're searching for "file name contains (BLANK)," and let the search proceed. Click on files chosen. The damaged tape's files will show starbursts next to the file name. Checkmarks and no stars mean the file is on a good tape. Go to the View Options menu and select Sorted Files - No Folders as the layout on the Mac, or hit Ctrl+H to toggle between Hierarchical and Sorted views in Windows. Sorting by backup date should group all files on the missing tape together in the list. Note that you don't actually want to complete the restore; this is just the simplest way to get such a list of the files on that tape.

Hot-swap hard drive backup option
Greetings! I understand from Dantz tech support that it is possible under certain conditions to hot-swap hard drives on a Mac. However they were not able to tell me a way to do this on PC's. I was hopeful that someone in this group might have, or know of someone that has, experience with using hot-swap hard drives for backup. I currently have Agate hot swap drive racks and software but Retrospect can't "see" the drives, even though Windows can. Since the price of drives is coming down faster than the price of high capacity tapes and the speed is much better for backup I would really like to be able to use hard drives instead of tapes for some types of backup.
