I’m starting to run into an issue with my backup strategy that is frustrating and looking for ideas.
Current system
Main Computer-iMac Intel (21.5-inch, Late 2013)
Time machine running to 3 different disks, 2 external hard drives and 1 RAID server. (Normally only 2 disks but one is trying to die on me so I’ve got a backup to my backup running)
Carbon Copy Cloner doing an automatic bootable backup daily to an external drive and also a full backup of my partition on the RAID that holds my picture files. Weekly find and replace corrupted files in this task.
Monthly bootable and picture file backup to a rotating set of 2 external drives. 1 is always offsite, 1 is here but in a fire proof media rated safe not near my desk.
Laptop-MacBook Air 4.2 (13 inch - Mid 2011)
Time machine backups when on to both an external hard drive and back to my main computer.
Monthly bootable backups using CCC with find and replace corrupted files to a rotating set of 2 hard drives again 1 is off site and one is in a fire proof safe.
Now the Problem
What’s happening is the weekly backup with the testing for corrupted files on the main computer takes 18-20 hours to complete on my main computer.
Ditto for the monthly bootable with testing for corrupted files on my laptop.
Even the nightly bootable backups are taking several hours each night.
I shut down my computers every night because we are solar powered. I want to reduce use during times we are using grid power. Sometimes the backups haven’t completed before I head to bed and want to shut my machines down. This forces me to either leave them running, or cancel that backup.
If I cancel then it starts up again next morning and reduces my performance on my computer while it’s running.
I’ve been through the hassle of a total failure of both disk drives and computer systems and the many hours it took to re-create stuff because of inadequate backups but I’m getting to the point of wondering whether the safety is worth it.
My original goal was to be able to get back running with everything but the last hour or so worth of work on a new computer within 48 hours. That is the time it would take to order a new computer with overnight shipping. We are hundreds of miles away from any Apple store although there is now a place to buy Apple products only 75 miles away so I could potentially reduce that to 24 hours if its during the week. They are closed on weekends.
I’m curious what other people are doing and what your time to return to operational status is from your backups assuming total hardware failure.
I am sure part of the issue is that my main computer is old enough to be a bit slow using USB drives for my backups, I have lots of data (Main computer is 939GB) and tend to open and change hundreds of files a day but still…
