Limitations

In this article, you will learn about the functional limitations of encrypting backup copies in AES-CBC 256 mode.

Selecting the highest encryption mode—AES-CBC 256—provides the strongest level of cryptographic security but introduces certain limitations for specific Xopero ONE functions.

Alert displayed after selecting AES-CBC 256 encryption mode.

Functionality limitations related to selecting a high encryption level are:

1. Running a disk image copy as an iSCSI disk.

2. Running a virtual machine copy as an iSCSI disk.

3. Running a virtual machine copy in Instant Restore mode (VMware).

The limitations described above result from the hardware performance of the machines used for real-time decryption of copies and their mapping as iSCSI disks or VMware virtual disks.

The use of AES-CBC 256 encryption does not affect the accuracy or reliability of backup and recovery operations.
