Acronis TrueImage Home 2011 Incremental Backup Issue

Thread needs solution

Hello,

On October 1, 2010, I created a full backup using Acronis TrueImage Home 2011 to an external 1TB hard drive. The file that was created is called Partition_backup__RECOVERY_OSC.tib and is approximately 525GB in size.

On November 7, 2010, I went back into Acronis TrueImage Home 2011 and figured there would be an option where I could just continue backing up where I had left off. I believe this was called an incremental backup in the 2010 edition. However, I do not see any options that allow me to do anything. It says that there is only 429.73 GB free on the external hard drive and thus not enough free space to backup my internal C: which now has 751 GB used.

So basically I'm asking is there a way to get the 751 GB that is on my C: onto my external 1 GB hard drive without having to delete everything off of it and then doing another full backup? Any assistance you can provide would be greatly appreciated.

When you create a backup task, you can specify how many incs to make before a new full is made. You might refer to the User guide:
http://www.acronis.com/homecomputing/download/docs/

How much smaller an inc is than the previous full depends on how many sectors have been moved or written to since the last backup. For example, if a disk defragger moves a bunch of sedctors around, ATI will pick up those sectors in the next inc. Also, win sys files and it's own backup (in win 7) will create newly written-to sectors during normal operation, which will be picked up by ATI in an inc.

Note also that you need about twice the space on your target drive as the total backup set-size. If you want to backup 750GB, your target shold be 1.5TB if you want to keep only one full or one full+Ince backup set. This is because ATI writes a new full (or consolidates a backup set) before it deletes the old full. This is intentional to prevent losing all your backups inthe event that a backup operation fails. This way, if a backup operation fails, you still at least have your previous backup for safety.

hope that helps.
