"but they offer "free" read-only snapshots, which can be very useful if your backup software or script does not perform its own snapshots." I really need to say two things here ... First, the zfs snapshots that are enabled on all normal accounts[1] can be your entire retention scheme. Which is to say, you can just do a "dumb" rsync to us ... no retention, no schedule, nothing - just an rsync every night - and on our end, we handle creating, maintaining and destroying your schedule[2] of full clones of your entire account. It's just like apples time machine, although more efficient since its using ZFS (bits) and not hardlinks (files). Second, as the parent implies, they are immutable. They are read-only and cannot be destroyed even by our local root. This means that if an attacker destroys your local data, and then gains control of your rsync.net credentials and wipes out your entire rsync.net account, the snapshots will still be there. You can't remove them. [1] But not on the discounted borg accounts, since we assume smart folks using borg set up their own retention schedule and that is how we make the accounts discounted - by not adding/rotating the snaps. [2] Yes, you can define whatever snapshot schedule you like - the 7 daily (<1TB accounts) or 7 daily + 4 weekly (>1TB accounts) are the default, but you can add whatever additional snapshots you like (more dailies, weeklies, monthlies, quarterlies ...) |
