TSGL: Acronis filling up disk space

[Marko Bjelac]

I have an external hard disk with about 150GB of space which I use only for
backup. I tried Acronis True Image and created a backup job which
incrementally backs up my complete documents disk. The used space on the
document disk takes up 51.6GB, but Acronis somehow fills the complete 150GB
backup disk with those 51.6GB he is backing up.

I set up the backup job to back up the whole partition/drive, not individual
folders. Is that the problem?

How (and with what back up program) to daily back up 52GB of documents on to
an external hard disk connected via USB? Of course, only a fraction of the
52GB is modified and added to the lot, but I want a program with incremental
backup which doesn't clutter up the backup disk.
