Stefano: RAID is not backup.

Me: Sync is also not backup.

Great article, Stefano, as always.

@stefano Good blog. Backups are indeed overlooked or neglected way too often.

@stefano Seen it go wrong way too often.

And, I know the feeling with a NAS crashing after just doing quite a lot of work, and just not having the backups updated...

It's more robust now with also some live (encrypted) backup to online storage, but something I still might have overlooked.

Recently I've added an extra place for the keepass database. After losing all hardware, the database would still have been save online. However, to access the online space I would have needed the KeePass >2

Thank you @stefano for sharing! I'm looking forward to this series; backups are far too often overlooked, and then people have to try to recover bits and pieces from the remnants.

For me, the place where I generally start is RESTORATION: what do I want a restore (full or partial) to look like? Then, storage media (local external HDD, USB flash drive, tape, cloud, …; RTO may drive this), taking into account integrity. A lot of choices are then driven or dictated by those.

@stefano Wow - 142 servers at OVH?
I have a number of them there too, only one was affected by the fire fortunately - but it was a total loss.
I have backups of course! So recovery was possible within a few hours.

@stefano Grazie mille Stefano! Your generosity with sharing your hard-earned knowledge through your blog and the no-strings-attached FOSS software you release, is very inspiring.
