The Backup Exec Desktop and Laptop Option supports file versioning. When a file is changed and backed up,
Backup Exec stores the changed file as a
‗revision.‘ Revisions are versions of a file at a specific point in time.
Backup Exec stores and maintains a specific number of revisions for all files in a backup selection based on the
backup profile.
ESG Lab tested Backup Exec
‘s file versioning ability in a series of tests designed to simulate a user creating and
editing a document over the course of a normal day. ESG Lab set the policy for this test to automatically protect
files on a simulated desktop user
‘s machine whenever a file changed.
A text file
containing the string ―Version 1‖ named ―Test File.txt‖ was created and saved in the My Documents
folder. The file was edited and saved two more times to create three versions of the file as shown in Figure 17.
FIGURE 17. CREATING MULTIPLE VERSIONS OF A FILE
ESG opened the Backup Exec restore dialog and verified that the Backup Exec agent had backed up each
version of the file automatically. As seen in Figure 18, three versions of the file were backed up, with the most
recent version identified.
