Administrators, Start Your Backup Engines...: Legato Networker 6.1
The latest in backup software handles the complexity of Windows 2000.
The newest release of Legato Networker (I looked at a release candidate
build) easily backs up the Win2K system state. Restoring the system state
is a more complex matter, and appendix B of the Administrator Manual describes
a detailed procedure. Networker backs up disk quotas, but doesn’t traverse
junction or mount points, so the target needs to be backed up separately.
Win2K encrypted file keys aren’t backed up, so you must maintain an alternate
copy of each key.
Networker uses a thoroughly distributed architecture, with client nodes
that can be backed up and control local backups and restores, storage
nodes that control additional SCSI devices, and a server node that manages
licensing and overall operations. Non-intuitively, you set up a backup
job by filling out fields in Manage Groups and Manage Clients screen.
Two kinds of backup jobs may be submitted: a User job, not considered
complete, and an Administrator job. You can set many options for a backup
job, including compression, priority (some jobs will be processed before
others), parallelism (how many streams may go to the server at the same
time), and remote access (granting the ability to restore). Another menu
choice supports Change Journal, which logs file system changes in NTFS
5.0. Networker can use the log to recognize file changes rather than traversing
the name space.
Given its mainframe heritage, Networker has some features (and complexity)
not found in the other products reviewed. It doesn’t support Microsoft’s
RSM for storage libraries, but does include support for storage silos.
Open File Connection (OFC) is Legato’s open file manager, and works with
NT 4.0, SP6a or later. For earlier Networker client versions, Legato recommends
St. Bernard Software’s Open File Manager. There is a disaster recovery
option available at extra cost. Networker includes the ability to clone
tapes, create a work list (if some items aren’t backed up because of server
failure, you may restart from where you left off), add customized directives
(e.g. skip spool or swap files), and manage multiple resources on the
same target by creating different groups and pools so that each item is
backed up to a different tape or at a different time.

managing backups and restores across your enterprise. (Click image

The wide range of options in Networker, combined with its support for
mixed OS and larger storage devices, makes it an attractive product for
enterprise-level backup. System administrators who need lots of control
over backup sets and locations, and fine control over every aspect of
backup and restore, will be especially pleased with this software.
