This post is both an acknowledgment of the speed of Duplicacy and a curiosity.
I just performed a 65 Gb backup to B2. Running the
backup command again shortly after the backup finishes, it checks that there is nothing new to be backed up in just 5 seconds …
INFO BACKUP_STATS Files: 8517 total, 66,085M bytes; 0 new, 0 bytes INFO BACKUP_STATS File chunks: 61450 total, 66,085M bytes; 0 new, 0 bytes, 0 bytes uploaded INFO BACKUP_STATS Metadata chunks: 8 total, 6,778K bytes; 0 new, 0 bytes, 0 bytes uploaded INFO BACKUP_STATS All chunks: 61458 total, 66,091M bytes; 0 new, 0 bytes, 0 bytes uploaded INFO BACKUP_STATS Total running time: 00:00:05
And the curiosity: How can Duplicacy scan 65 Gb of 8517 local files, compare with the chunks, and find that there’s nothing new in just 5 seconds?
