BitFolk's backups currently use rsnapshot, which works like this: - rm -r hourly.5 - mv hourly.4 hourly.5 - mv hourly.3 hourly.4 - mv hourly.2 hourly.3 - mv hourly.1 hourly.2 - cp -al hourly.0 hourly.1 - rsync […args…] root@your-vps:/path hourly.0/your-vps/ That happens at every backup run, so potentially 6 times a day. Also once a day a "du" is needed against each customer's backups in order to work out exactly how much has been used and the differential usage between iterations. All of this is obviously a large amount of IO and in fact when the backup VMs were on hosts with HDDs it was getting difficult to have a backup run complete within 4 hours (the maximum available run time at 6 times per day). So I don't think I can risk putting backups on HDDs again as they will end up running too slowly. Previously I offered backup space at a 25% discount on the experimental deduplicating platform and if that proves stable and reliable then I will adjust the backup prices to that, but unfortunately I can't see a way to make it any cheaper than that.
