Oh - I use Acronis - I'd like to clarify this. Acronis does intelligent incremental/differential, down to the granularity of which files have changed. But it relies on the file timestamps, and it sends the whole file. This means Acronis has two problems: TrueCrypt images intentionally leave the timestamps unchanged. So Acronis never sends the updated TC file during incrementals. and Whenever a Full image is sent ... Acronis is not able to handle sparse files intelligently. The whole file will send, and it will take forever, and it cannot be restored sparsely, even if you try. The same is true for Time Machine. _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
