This is the way, Arq is dead simple, cheap, and so is Wasabi.
Quoted from my own past comment[0]:
1. The client will lie to you and you never know what’s really backed up. Even if you use the secret alt-click to force a full drive scan, it can still miss files and tell you fully backed up when files from days ago are still nowhere to be found. Luckily I’ve never actually needed to do a restore, but I almost thought I did one time and would have been furious at all the missing files I noticed.
2. This might not matter to some people but absolutely no meta data is backed up.
