I want to be very clear here. I have used SmartBackup for a long time, and I loved it. It works great and is reliable to use ... but with a HUGE caveat. DON'T USE IT WITH NETWORKED DRIVES! I have multiple back ups of many of my drives, and one was a "shared" drive between many computers in my home. I use the airport's usb port to "network it."
This drive failed last night, so I went to my backups relieved that I had SmartBackup religiously backing the drive up. Unfortunately, the folder was completely empty. NO BACKUPS. It had a very long log of how it was backing it up everyday, but somehow, it was not connecting to the drive. So, it thought there was nothing to backup.
I would give this software 4 stars if it were not for this realization of its massive Achilles heel. If it cannot give some kind of warning when it doesn't connect to the networked drive or finds no files or something ... then you are as good as dead when you find no backups when you really need them. I am having to find another solution, today. This is a sad day.
Again, this complaint is just about networked drives. If you have none, then I would recommend this software. All my other backups are in perfect shape.
