Time Machine vs Carbon Copy Cloner (and Versioned Backups vs Flat Clone)
Seeking advise on local backups for a MacBook Pro.
- Time Machine — via WiFi (hourly), to an external HDD attached to a different/host Mac.
- Carbon Copy Cloner : Versioned Backups (using CCC Snapshots and SafetyNet) — via WiFi (scheduled nightly), to an external HDD attached to a different/host Mac.
- Carbon Copy Cloner : Flat Clone (without CCC Snapshots and SafetyNet) — via direct-attached USB SSD (manually weekly).
[Q] I see how a CCC Versioned Backup can be better than TM, because CCC is more reliable and configurable. I worry about TM's reliability, bugs, and possible corruption (caused by interrupting a backup when the source Mac is closed/moved). But is TM potentially more versatile, being a native macOS option for Recovery mode?
[Q] I see how a CCC Versioned Backup (WiFi/auto/nightly) is better than a Flat Clone (USB/manual/weekly), because it runs automatically and historical versions are available. But, is a CCC Flat Clone ever better or more usefaul than a CCC Versioned Backup? Is a Flat Clone possibly easier/safer to restore from? Is the only real downside of a Versioned Backup that the disk should be 2-3x larger, and thus (for me anyway) on HDD, rather than SSD?
[Q] Using CCC to replace TM, would I need both CCC's Snapshots AND SafetyNet? Or just Snapshots? I'm not quite clear exactly how CCC SafetyNet relates to Snapshots.
- Source Mac: 2021 MacBook Pro (M1), on Monterey 12.2.1
- Host Mac: 2013 MacBook Pro, setup as a home server via ethernet, on Big Sur
- CCC: v6.0.5
Thanks for any thoughts or insight.
