I've started using Drive SnapShot for disk image backups. Previously I used Acronis True Image (with no complaints about ATI). I do my backups at night using Windows Task Scheduler running a batch file to create an image of disk C to disk E. I like the idea of the small size of Drive SnapShot, but I have a few questions on which more knowledgeable people here may be able to advise. First, although I use the -L0 parameter to create a single sna image file, the result comes out as a number of sna files each of whose size is 1.45GB. (Upon closer inspection, the sna filesizes actually are not exactly the same, if one counts the filesize in bytes.) Part of my batch file is: What am I doing wrong? My second question is, why does the verification testing of the backup take so long to do? For a backup of 58GB, completed in about 34 minutes, the verification took about two hours to complete. My third question has to do with the difference between incremental and differential backups. I read the explanation given in Drive SnapShot's website about the advantages of differential backups compared with incremental backups, but I would be interested to hear other people's views as well.
