Reinstalled and re-configured the UPS gubbins on the home server. Data should be safe in the event of a power cut.
And for double bonus points, I've finished tidying up the ZFS backup scripts so snapshots over 60 days old on the backup server are removed and the storage pools scrubbed on a monthly basis.
I've written everything down, which I'll be publishing as a full guide in the next few days.
All I need to do now is image the home server and set-up some sort of regular file-based snapshot, both of which should be fairly trivial, especially as for the latter part I can cull scripts I've written for backing up VPS boxen.
And then I can continue with other projects, including finishing the website for a fellow patron of yACF. I'm slightly embarassed it's taken so long, but then life does keep getting in the way!
