I believe strongly in disaster recovery preventative measures. On my Macs, I use Time Machine religiously.
And I do a complete TM backup every so often IN ADDITION to the normal incremental one, as a total snapshot of my system in case the TM archive gets eaten or corrupted.
And I use a variety of separate media -- no point having all your backup eggs in one basket.
And my main archive is a mirrored RAID-1.

Everything you said is excellent advice, regarding being careful bringing data into the Mac, and backing up your data. I also use a mirrored RAID-1 external enclosure for my main archive where my Time Machine backup folder resides. Here is why a full TM backup is warranted every so often:
Sometimes Time Machine will have a corrupted incremental. When I have migrated data from an old drive to a new one, sometimes not all the Time Machine incremental backups get copied due to a corrupted file. Rarely happens, but it can happen. I use the Finder Copy operation to copy the backup folders between hard drives. Promptly followed by a full backup to the new backup folder. Recently upgraded to a pair of 6TB drives from 3TB in the RAID-1. I keep the old ones with the data for a while as insurance.
