Daily Hack #78

When did the backups die

Digital Forensics & IR Difficulty Medium ~4 min +10 XP

A restore request just failed: last week's database archive unpacks to nothing. The nightly job has reported OK every single night and the dashboard has been green the whole time, so nobody noticed. Log in to the backup host, work out from cron where the job writes its log, and read that log night by night. One night carries a warning that resolved by itself, and it is not what you are looking for. You want the first night the archive came out empty while the job still called itself a success. Submit that date as YYYY-MM-DD.
