Yes, typo, but perhaps Freudian ... It's a backuppc archive that's been
running for years (since before other filesystems knew how to create
files quickly) and has millions of hardlinks. The last time I tried to
copy one with a non-image method I gave up after three days - and that
was a smaller drive. This is a 250 gig drive about 75% full holding
about 725 gigs of raw data before backuppc's linking and compression
operations.
I have a 3-member raid where 2 are internal IDE drives and the 3rd is a
set of external firewire drives that I periodically connect and sync
(takes a couple of hours) and then rotate offsite.
If there is a better way to do that these days with LVM snapshots or
something, I'd consider changing the approach even if it means starting
over, but I need some way to do an image copy with no downtime - or just
a momentary unmount of the filesystem so the copy is clean.
