[Borgbackup] Question about borg remote/local setup

[David Thibault]

Actually, when I started this thread I was looking into using S3 instead of
EFS, because it's way cheaper. S3 didn't work because it wanted to edit
files. Then I switched to EFS.

However, with this hybrid setup, keeping everything but the ./data folder
on the local disk and the ./data folder on S3 does actually work...at least
so far...it's creating block files in ./data.  That's further than it got
before.  I'm thinking the hybrid approach with s3 mounted via RIOFS might
be the way to go.

Best,
Dave
