Incremental backup of one large file
Hi,
i using Acronis True Image Home 2009. Situation:
- one large file - 4GB,
- a create full data backup from this one file, without compression,
- next, i change only one byte in this original file, at the beginning,
- now i create incremental databackup and surprise, incremental data file has size again 4GB.
Why ATI 2009 don't compare file content?
True Image Home 2010 work on same principle?
Thanks.

Thanks for answer. Btw, mentioned files is regular file from TrueCrypt, partition in file, 20GB.
I try design safe way to backup private data (incremental, difference) with preservation of TrueCrypt privacy.

With the next verison of ATI Home 2011 you'll be able to back up separate files using Non-stop bakcup feature. It will back up only so called "deltas". This means backing up not entire changed files, but only differences between new and old versions. For example, if you use Microsoft Outlook or
Windows Mail, your pst file may be very large. Furthermore, it changes with each received or sent Email message. Backing up the entire pst file after each change would be a big waste for your storage space, so Acronis backs up only its changed parts in addition to the initially backed up file.
Nowadays, in ATI Home 2010, Non-stop Backup is only availbale for image backup. But anayway, we can exclude all the files except the ones you need.
