I am looking for some backup software. Ideally that could do differential straight away. I have 'acquired' something called Genie Backup Manager which apparently is (one of?) the best. The thing is there is no option to do a differential [straight away]. I was hoping it would give me the option of setting something like this: Differential > From [Date] > To [Date] > [Choose Folder] > Backup HOWEVER, looking at this and other software it appears that it MUST do a full backup first and it saves the information in a 'catalog' file which it then uses to reference dates etc. Well there are two systems I need to backup. Doing a full backup on both of them is tedious when there are only a few files that have changed in the past week. I hope this is clear. Does anyone know a customisable backup software where I could set that I want it to backup modified files between a certain period? If I did a full backup of both systems it would take four hours total. A differential backup would take 15 mins to half an hour max... Thanks in advance.
