My Backup of December 14 (Full Image backups) had 5 slices. My Backup of December 19 had 9 slices. Only difference in storage space was possibly the addition of a printer with its Photoshop application. My backup of December 22 done after deleting the December 14 archive and this latest one has 13 slices. Therefore, Backups are increasing by 4 slices each time... is that significant, does it mean anything? And why does the Backups now take over an hour when the first one took 26 minutes?
