I assume power consumption on that is 5W max since it's a usb based
device with no external power source.

That is the plan, though I intend to offer the hosting family members
space on the system too. So I'd need at least 1 TB just for stuff at my
house and room to grow hence the interest in 2 TB drives.

Good point, rsync always scares me, guess I just need to run all the
commands in test mode 1st(I have tendency to create a duplicate of a
directory as a child directory instead of syncing). It might be good
though since I probably don't need to send offsite every night.

That one's still to be decided depending on how I back things up. Right
now my Photos are add only (and my next big project is to digitize a old
record collection); never delete and my system backups are
Full/incremental keeping between 6 months and a year. Ideally of course
all these files main versions actually live elsewhere.

Thanks, a little more pricing and I think I'm close to a purchase,
