I cannot get a successful disk-image creation of the primary C drive. There is a definite possiblity that I have other problems on that drive, since it will no longer do a check disk run either (locks up on step 4). However, just in case the error is: Read Error (0x70003). If this was due to just one file or segment, could not TI be programmed to simply move and complete the image, but list the missing sections on the log (ie. usea 'backup created, but with errors' message) Also: - Previously, I had backup jobs pause because they had similar read errors on certain files, but the job did not completely cease, it just waited for a 'Retry' or 'Ignore' prompt from the user. Is there an 'unattended' selection somewhere that would tell the program to automatically continue on its own after a certain nbr of retry failures? Finally, I'm still not totally clear on the differences between an incremental B/u and a differential one. Seems like they both only add on updated or new data, but incremental will do so with a new file every time while differential recreates just one additional (from the original full-backup image) second file, is that correct?
