I think a better solution might be to keep the encrypted fs on a single normal LV. Take a snapshot and send to remote. Keep the snapshot around. On next upload, take a 2nd snapshot, and send the diff between the two snapshots. The diff can be efficiently computed from the COW tables - accessible as dw-nn devices. After sending the diff, delete the 1st snapshot and go back to "keep snapshot around". --------------030606050406030705040102 Content-Type: text/x-vcard; charset=utf-8; name="stuart.vcf" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="stuart.vcf" begin:vcard fn:Stuart Gathman n:Gathman;Stuart org:Business Management Systems, Inc adr;dom:;;4001 Williamsburg Court;Fairfax;VA;22032 email;internet:stuart@bmsi.com tel;work:703 591-0911 tel;fax:703 591-6154 tel;home:703 378-9641 note:AIM: SDGathman x-mozilla-html:FALSE url:http://bmsi.com version:2.1 end:vcard --------------030606050406030705040102--
