When restoring image file, can not change destination partition size?!

Thread needs solution

I backup CentOS 5.5 using ATI2016, when restore from that image file, the destination partition size can be seen but can not be changed?! the destination partition size was gray and can not be changed, the size bar can not be moved.

 

The HDD is 250GB, after installed CentOS 5.5, I check the disk status and find that CentOS only occupied about 3.5GB, but when using ATI2016 backup, it use all diak space to backup to image file, I want to shrink the partition size to 10GB.

Johnny, welcome to these user forums.

My understanding with how ATIH 2016 handles Linux file systems is that it tends to default to using sector-by-sector which will result in the whole disk being backed up.

The ATIH 2016 User Guide: Supported file systems states the following:

The Ext2/Ext3/Ext4, ReiserFS, and Linux SWAP file systems are supported only for disk or partition backup/recovery operations. You cannot use Acronis True Image for file-level operations with these file systems (file backup, recovery, search, as well as image mounting and file recovering from images). You also cannot perform backups to disks or partitions with these file systems.

This suggests to me that other operations such as resizing the partition is not supported - only plain backup and recovery.  You would need to use a different utility to resize the partition such as Gparted in Linux.
