Backup Software
There are many types of products for backup and restore operations.
If you have a small environment and are performing local backups, the most obvious choice is to use the backup software included with Windows. Microsoft ships a “light” version of Veritas’ Backup Exec[44] with both Windows NT and Windows 2000. This is called NT Backup. NT Backup can only be used to perform local backups.[45] I briefly describe this software in the next section; however, I recommend instead choosing a full-featured backup software product with features such as disaster recovery.
If you are doing remote backups and restores over the network, there are many choices. Available products include:
- Computer Associates’ ArcServe
Software for backing up mainly Netware and NT systems.
- Legato Networker
For heterogeneous networks that contain a mix of NT, Unix, and other systems.
- Veritas’ Backup Exec
An excellent product for backing up and restoring Windows NT/Windows 2000 hosts.
- Veritas’ Netbackup
Another piece of software for large heterogeneous networks.
Personally, I like Veritas’ Backup Exec’s ability to restore a complete system from a bootable set of floppy disks, a bootable CD-R/RW, or a bootable tape.
When deciding on which backup software to use for remote backups, consider the following:
- Is the product suitable for use in a firewall environment?
Does the product operate on dynamically assigned or fixed ports? How many ports are required?
- What kind of authentication is used?
