Yeah I guess it probably makes more sense when it’s my business… Maybe not if you’re an employee at some corporate randomly hosting backups of your dog photos.

I have a 120TB unraid server at home, and a 40TB unraid server at work. Both use 2 x parity disks.

The critical work stuff backs up to home, and the critical home stuff backs up to work.

The media is disposable.

Both servers then back up to Crashplan on separate accounts - work uses the Australian server on a business account, home used the US server on a personal account.

I figure I should be safe unless Australia and the US are nuked simultaneously… At which point my data integrity is probably not the most pressing issue.

Feels like this is the sort of important information OP should have included in their post.

I’ve been using Nextcloud since it forked from OwnCloud (… and used OwnCloud before that). It’s gone from a VPS, to bare metal on dedicated hosting, and now self hosted as a docker container because we’ve finally got fibre internet.

I’ve got around 6TB or so hosted for my small business, with shared directories for different levels of file access, shared contact lists, shared calendars, and a publicly accessible area for things like email attachments (works with a Thunderbird plugin to automatically host and link large attachments with a password) and uploads from customers (they can only upload, no viewing or deleting).

It’s incredible, and I’ve never had the issues people complain so much about. The worst I ever experienced was using snap and occasionally an automatically updated version simply wouldn’t work… So I’d just roll back to the last version and manually update a few months later when I remembered.

Currently using the Nextcloud AIO docker image which includes Borg backups. They get stored on another disk to Nextcloud, which gets automatically backed up to Crashplan.
