alistair Posted August 25, 2006 Report Share Posted August 25, 2006 We have about 200GB of data to backup using Retrospect 7.5. What I'd like to do is firstly do a backup to external harddrive then switch to doing nightly normal backups to DVD. From doing a few tests & reading relevent parts of the manual I can't work out a way to do this. Whenever I switch the backup set from the set that contains the hard disk to the set that contains DVD Retrospect starts a compete new backup & asks for enough DVDs to fit 200GB. Am I missing something or is this not possible? Thanks Alistair Link to comment Share on other sites More sharing options...
nekr0phage Posted August 25, 2006 Report Share Posted August 25, 2006 Hi Alistair, Retrospect's comparison feature is based on information stored about files in a backup's catalog file. Each backup set has its own catalog file, therefore each backup set will only increment upon data already stored in that backup set. You cannot run a "full" backup to one set, then run "incrementals" to another set. Link to comment Share on other sites More sharing options...
alistair Posted August 25, 2006 Author Report Share Posted August 25, 2006 So to use DVD as a backup medium we need to have enough on hand to do a full backup first time. About 46 last count :-) Cheers Alistair Link to comment Share on other sites More sharing options...
nekr0phage Posted August 25, 2006 Report Share Posted August 25, 2006 Alistair, Yeah. Hopefully blu-ray or hd dvd will be available soon, that'll cut the number of discs way down. Link to comment Share on other sites More sharing options...
