Why my back-ups failed

So here's a funny little thing I've never thought about. I live in a country where we have summer/wintertime, so the clock was set ahead an hour tonight. Every morning when I wake up, the first thing I do is open my e-mail and check for the e-mail from ProxMox telling me my back-ups were (hopefully) successful. This morning started a little different, no e-mail. I go downstairs, start my PC, log in to the ProxMox webgui. No errors, nothing about the back-up in the logs. So I go into ProxMox back-up server, once again all green checks across the board, but no mention of last nights back-up. After about an hour and a half of investigating it hit me, my back-ups run at 2:30 AM. The clock was set ahead by 1 hour at 2 AM, so 2:30 AM never happened last night and now I feel like an idiot that I didn't think about this sooner. submitted by /u/KadaverSulmus [link] [comments]
