I'm using borg and I honestly like it. Not ready to only rely on it. I try to use the 3-2-1 principle of backup strategy and borg is really a space and bandwidth saver! My collection grew from few Gb to some Tb. It's already more than a year old and I was wondering whether it's better to start a fresh new repo every year or to let grow the original one until it reaches a certain size? Any recommendations from ppl that used it for +2 years?
