I use multiple backup & recovery methods. Some backups happen hourly, some fire off automatically in the wee hours of the morning and others I do manually when I feel the urge. It is generally a good idea to have more than one backup & recovery method and it is vitally important to TEST to ensure that the recovery part works. No sense in backing up religiously only to find out later that you don't know how or can't actually recover what you want from your backups.

For every computer around the house:

- We use Time Machine for hourly backups & Carbon Copy Cloner for automated nightly backups. Time Machine backs up hourly to SSDs that are locally attached to each computer because they're very fast. Time Machine is ideal for very easily rolling back to versions of your work in previous hours in case you made a change that you didn't intend to, or deleted something you wish you had kept.

- Similarly we create fully bootable backups to those locally attached SSDs on each computer using Carbon Copy Cloner. The SSDs have separate partitions for Time Machine and Carbon Copy Cloner backups. The bootable backups fire off at about 5 a.m. each morning. The huge benefit of bootable backups is just that, you boot from them. If the disk in your computer starts getting flaky or dies, boot from the external bootable backkup and keep on working where you left off. No need to reinstall your OS, redo all your settings, and recover your important files separately. Just boot and keep working. Carbon Copy Cloner is also used for our non-bootable backups to NAS and these fire off round 12:30 a.m. each morning.

- And even though the NAS has redundant disks in a RAID group, it's still a good idea to backup the NAS itself. Even though the disks in the NAS are redundant, consumer NAS have several Single Points of Failure (SPOFs) that can take it down. My larger DS918+ NAS is attached an external 8TB Western Digital USB disk. The NAS launches HyperBackup to periodically back itself up to the external 8TB WD USB disk. This setup is also used for archiving old photos, tax documents, and other important items.

For the music setup:

- The smaller DS718+ NAS is used for music duty only. I use it to run Roon Core. All my music is ripped to this smaller NAS and Roon Core streams it to whatever network endpoint I want in our home. The music on this NAS is backed up to an external 4TB 2.5" disk. The music folders are also periodically backed up to the other larger DS918+ NAS. If you want to take it a step further, you can keep a couple backup disks offsite.

Since these backups are automated, I never have to wonder when I did my last backup. Even if I rip or download new music, I know it will be automatically backed up. After extensive testing, I can honestly say that my backups are on reliable autopilot.
