They needed someone with a CCNA certificate for hardware discount reasons, and mine was going to expire the day before the interview
Did they demand the proof of the cert, including the expiry date?
Because if you did clearly also mention - and also showed proof - of the renewal exam, that’s grade-A bullshit. They were searching for an excuse.
It is Duplicati, and IMHO restores work best if they aren’t restores-in-place. As in, dump the restores in a central location then drag-and-drop the data into place. Most of the issues I have heard of involve restoring data and settings back to where it originally was backed up from, and restoring directly back to those places - other than fully user-controlled directories, such as Documents or Photos - seems to be problematic.
Other than that, I have been using it for nearly a decade and have done a number of restores - after total drive deaths, so not just accidentally deleted files - to great success.
The downside is that tweaking backups from within the hidden
C:\Users\[username]\AppData\
directory involves many days of whack-a-mole to exclude untouchable normally-in-use files so you don’t get scads of errors in the backup process. Plus, there are a fair number of entries in there that don’t really need backing up. But once you get that to settle down, it’s largely smooth it’s-set-so-forget-it sailing.
