I recently upgraded to El Capitan and while checking the system logs I noticed lots of errors about not being able to delete old backups (thin backups), such as:
2016-01-10 05:22:48,193 com.apple.backupd[5904]: Starting post-backup thinning
2016-01-10 05:22:49,319 com.apple.backupd[5904]: Error: Error Domain=NSOSStatusErrorDomain Code=-36 "ioErr: I/O error (bummers)" deleting backup: /Volumes/Time Machine Backups/Backups.backupdb/fünke/2016-01-01-213437

Disable CrashPlanService on OSX
Since I run CrashPlan on my QNAP to back up my personal data, yet I still want to use the CrashPlan GUI on my Mac, I don’t need the CrashPlanService running in the background on my Mac all the time.
Update CrashPlan on QNAP
It’s happened to me twice now: CrashPlan stops backing up my files apparently due to a failed software update. I usually don’t know CrashPlan has stopped backing up until I get the weekly email status update. Fortunately, the files that I back up to CrashPlan are not changed often at all, and missing a backup for a couple days isn’t the end of the world.
