In this video, Kevin Dankwardt reminds us of the importance of backups and discusses a variety of approaches. We use tar, cpio, rsync, and cron for backups and discuss Relax and Recover.
- [Instructor] Let's talk about…backing up and recovering.…Things go wrong,…data gets lost.…You know it's going to happen.…Certainly hardware can fail.…But if you have lots of redundant things then,…that really helps to avoid that problem.…But a really common reason to lose data is you, right?…Where you had a typo,…and you remove something you didn't mean to remove.…That's pretty common.…So no matter how reliable…your RAID system or your disks are or,…copies of stuff everywhere,…if a little typo can wipe it out,…then you're at risk.…
So we all know about doing backups.…We've all felt the pain of not doing a backup.…So there's some easy ways to do some backing up…on Linux and then there's some complicated ways.…So let's talk about it a little bit.…So we got commands like tar and cpio.…Which are widely used.…And essentially they can make a…copy of a directory and stuff in it into a file.…And then you can put that file some other place.…And then you can extract it out…to get old copies of things.…
Little more sophisticated is dump.…
