I have a NAS at home with ZFS snapshots and nightly offsite backups. What's so hard about that, or how is it less durable than your S3 solution?

Nightly? what happens in between and how many different sites? What happens if your Internet goes down one night? How many parity drives do you have? Will the array survive replacing a drive or will another one die during the sync will you lose data if that happens?

S3 takes replication seriously to a professional level, when you upload a file to S3 the chance of s3 losing it is capped by the chance of a civilization killing asteroid hitting the earth.

		Yes. Nothing, one site. The backup gets taken the next night. One. Yes. Yes. What happens if your drive dies just as you're uploading the file to S3? Why are we comparing the durability of S3 to the reliability of my Internet connection, instead of to the durability of rsync.net?

How often are you testing those backups? What kind of monitoring do you have? Do you pay attention to it? Skip any of those and it's just a prayer.

		They're zfs snapshots, assuming you're actually taking them, a send/recv shouldn't cause any problems... (ignoring the hole_birth and encryption bugs from the 0.6.x days - to my knowledge, they should both be resolved by now)

		Every day, healthchecks.io, yes.

How much do you pay for offsite backups? How durable are they?

	▲	PunchyHamster an hour ago \| parent \| next [-]
		the answer is always "durable enough", purely because the chance of 2 independent backup copies failing at same time is vanishingly small

		I think around $50/yr for around a TB? It's rsync.net, so I think very durable.
