Backup File Encryption

ShadowProtect can encrypt and password-protect backup image files. This is particularly useful when storing backup image files on a network or off-site. To mount or restore a protected backup image file, you must provide the correct password. If you do not enter the correct password, or you forget the password, you cannot access the backup image file. Make sure the password is stored in a secure location as Arcserve cannot bypass the encryption on a backup image files without the password.

You may select from three methods when encrypting a backup image file.

• RC 4 128 bit (Fast): Faster but less secure than AES 128-bit.
• AES 128 bit (More Secure): Faster but less secure than AES 256=bit.
• AES 256 bit (Most Secure): Slowest but most secure security option.

In addition to bit strength, the password used to secure the backup image file can affect security. Use the following password guidelines to ensure the highest level of backup image file security:

• At least eight characters in length
• Random mixture of upper and lower case letters, characters, and numbers.
• Do not use words found in the dictionary.
• Change passwords regularly especially if you suspect your password has been compromised.
• Note: ShadowProtect passwords are case-sensitive and only support alphanumeric characters.
