I use the drive-to-drive backup and it works well. I don't have as
much data as you, but a full drive-to-drive backup takes 2 hours here
nonetheless. But I get incremental backups as well.
Here's the secret - if you do a backup using the Linksys
webpage "start backup now" button, it *WILL* do a full backup every
time. However, if you SCHEDULE the drive-to-drive backup, it will do
incremental backups after a full backup has been performed either with
the "start backup now" button or if it does a full backup (if it needs
to) when the scheduled time rolls around. Actually, I believe it's
syncronized as opposed to incremental since files removed from disk1
are removed also from disk2.
Elaborating further... I have drive-to-drive backups enabled 1 day a
week. My slug hasn't done a *full* backup in about 6 months. But the
contents of both drives are identical (I check every now and
then :) . If I ever want to do a full backup (for whatever reason), I
go to the webpage and click the "start backup now" button, takes 2-3
hours, then finishes. On the next scheduled backup time it does
incremental backups from then onward.
Caveats.. If you disable the drive-to-drive backups and/or change
disk2 in any way, and then re-enable the drive-to-drive backups, the
system will think disk2's a new drive and on the next scheduled backup
time it *will* do a full backup. Disk2 should be transparent.
If this is what you're aiming for, give it a try. Schedule a backup
time in the webpage for some time in the future. Hit the "start
backup now" button to get a full backup, let it finish, and see what
happens when the SCHEDULED backup time arrives. Has worked flawlessly
here for quite some time.
p.s. Works with V2.3R29 and V2.3R63 linksys firmware. And a shame
it's not documented.
Hope this helps!
