Finally did something I've been meaning to do for ages: created a full backup of the processed page-images from Lettuce to Rutabaga. This took literally all day (I throttled rsync a bit to make sure Lettuce didn't struggle). I realized I could also have logged on directly to nfs.tapor.uvic.ca, taking Lettuce out of the equation; might do that in future. This is the process: ssh into lettuce, navigate to the coldesp www folder, and run rsync --verbose --progress --stats --compress --recursive --times --bwlimit=10000 jpg_scans/ -e ssh mholmes@rutabaga.hcmc.uvic.ca:/"home/mholmes/backups/Martin/Colonial\ Despatches/www/jpg_scans/" . I did the equivalent for the maps directory as well.
