My comment:
"BackupBuddy was a huge waste of time and TRASH for me. Others disagree. jkware's CardBackup "glitched" once on me but still restored okay, and has been flawless every other time. TealBackup glitched once (on a test) because I did not disable all hacks first (it's picky about those!). But both work, both have been tested with hard resets."
I think the only "prayer" you have for T5 backup, based on reading the latest on several programs and the Tealpoint forum discussing possible problems related to NSVS systems, is: TealBackup and whatever YOU ALL have found that actually WORKS.
Please understand I'm not simply "pushing" TealBackup here; I IN FACT prefer CardBackup from jkware due to speed (very, very quick, and restore WORKS) - but THAT IS ON A T3. The T5 is a different animal, and although some have claimed to have problems with TealBackup using a T5, at least it works "mostly."
I don't think there is a FLAWLESS T5 utility "yet," but if I had a T5 I'd go with the "slower" TealBackup for everything (I use it to make encrypted backups of about 12 databases, and that takes up to 20 seconds alone!). Choosing no encryption and "automated during the night," would of course eliminate some waiting time.
A good article on NVFS basics, which is the problem behind TealScript running slow on some LifeDrives and the "backup problem" in newer units:
