[QUOTE="MacInWin, post: 1627207"] Restoration of OSes is always ugly. It is far better to reinstall the OS, then restore the rest of the system. At least then you know you have a bootable system with all the essential components in place. An untested backup is just a collection of files. Might be useful, might not. Making the backup is only step one. 45 years here, running everything from my home network to managing a 24/7, we-never-close national defense data center with 6 mainframes and 23 mini servers and a worldwide network. BTW, we did have an outage at that center when all cooling (including backup units) failed simultaneously. Thermal shutdown on every machine within 1 minute because the temp in the center hit 140+ degrees (F) (it went off the edge of the recorder paper that stopped at 140). Took 8 hours to cool it back down to 75, which was when we restarted the equipment. Backups worked for that one! I was getting phone calls from the Pentagon hourly... I don't trust computers. Any of them. Too many ways to get borked. I make backups twice daily, to two different backup drives using two different applications (TM and CCC) and I test the backups once a month by booting from the CCC drive and restoring something from the TM drive. Still no guarantee, but it's better than nothing. [/QUOTE]
