I have set up a 40gb external hard drive ("F") as a supplemental backup of my "C" drive, which has only about 25 gb of files on it. To ensure that I will have sufficient space on the "F" drive , at the start of each month I erase the accumulated files( not those in the Secure zone), do a full backup, and set Acronis to do an incremental backup every other day. The first time I did this, I got a "system not available" or some such error, which I finally solved by deleting and reinstalling the Acronis program. Although this didn't take long, is there a way of deleting last month's backups without having to reinstall the program? If the backup disk gets full, will incremental backups fail, or will Acronis automatically delete the oldest incremental backup? Assuming I have suffficient disk capacity, could I save the backups in uncompressed mode, so they could be accessed off the "F" drive directly, vs. having to mount a virtual "G" drive? Thanks in advance.
