It’s great that Leo recommends daily Incremental backups, but I suggest that rather than simply doing them on Files, there are big advantages to doing them on the entire Disk Image.
Doing so takes a little more time to run for the periodic base backups, but virtually no more time for daily Incrementals.
And the advantages are very great: one saves all the time of reinstalling and reconfiguring programs, and running updates, when one’s system drive fails or is hit by malware.
And Image backups can do everything that File backups can: one can always grab files and folders out of the Images.
I’ve been doing this for a quarter century, and so nothing that’s happened to a backed up drive has ever been more than a momentary inconvenience. (Of vital importance to me since I have limited hand use because of carpal tunnel.)
I know some people like to have to reinstall their OS (or roll back to the initial Image Leo recommends), but there’s nothing stopping them from doing that if they want to just because they have another option.
(On Windows I had been using Acronis, but I’m thinking of switching to Macrium.)
