![]() I have both the traditional and long-proven utilities Carbon Copy Cloner and SuperDuper!, which originated as volume duplicators, so should be ideal for this task. This isn’t as straightforward as it might seem. What I therefore want to keep is a copy of the System volume for each updated version of macOS, which don’t have to be bootable. This is perhaps inevitable given my interest in macOS, and I accept that it’s an unusual habit. The most common reason for me to access my old Time Machine backups was to dig back through old versions of macOS, to find previous releases of its tools and other system files. This article considers the first two on that list, backups which are made once a day or less frequently. My next task was to decide which backup utilities to use for each of those. a Time Machine backup of that same working folder every hour.īeing smaller, these enable me to use the four SSDs in my ThunderBay enclosure as individual disks, rather than requiring a RAID array.a full copy of my main working folder on an external SSD updated hourly.a full copy of my ~/Documents folder updated hourly.a full copy of my Data volume and its external supplement, updated nightly. ![]()
