What frequent tests should you perform to ensure the integrity of backup settings and media?
Click to show answer
You can perform a test restore and validate the files. You can run an integrity check on the media by using, for example, chkdsk on a hard drive used for backup. Backup software can often be configured to perform an integrity check on each file during a backup operation. You can also perform an audit of files included in a backup against a list of source files to ensure that everything has been included.
