Less than a day for disaster recovery on fresh hardware? Same as my case. As you say, good enough for most purposes, but I'm also looking for improvement. I have offsite realtime replicas for data and mariaDBs, and offsite nightly backups (combo of rsnapshot, lsyncd, mariaDB multi-source replication, and a post-new-install script that setups almost everything in case you have to recover on bare-metal, i.e. no available VM snapshots).

Currently trying to reduce that "less than a day" though. Recently discovered "ReaR" (Relax and Recover) from RedHat and sounds really nice for bare-metal servers. Not everybody runs on virtualized/cloud (being able to recover from VM snapshots is really a plus). Let's share experiencies :)
