Sofar I have only used Fd_ISR with a few snapshots and a number of archives. I am now trying to get familiar with imaging software and I wonder how to best manage this. Here is what I am thinking but please correct me if I am wrong. 1) Snapshots are convenient for immediate rebooting into another set-up, however they do take up some space. This is not so much an issue on the harddrive (enough space nowadays), but will increase scanning times for AV or imaging times for creating images. So I guess I will reduce my snapshots to Work, Secondary (to reboot quickly) and possibly one special function snapshot. 2) Archives - useful for quick recovery of earlier setups - stored on a separate internal and external drive for security 3) Images - as additional backup in case of hardware failure, again stored on separate harddrive and external drive My intention is to only image the OS as my data is on a separate internal harddrive with backup to an external drive. Does anyone use images for "data drives"? Now I realise that some users here have their own finetuned strategy,probably developed and improved over time. If someone would like to share their back up plan, I would be very interested - primarily how to combine the three, how many snapshots/archives/images to keep, how or when to prefer one over the other ... I am sure there are many aspects I have not yet thought about.
