system including Unix and OS/2.

• Downed Server Backup

SnapBack/DOS will back up a downed server. This feature

can be used to create an intermediate backup prior to

attempting server file repairs. If a repair attempt fails or

causes additional corruption, the intermediate backup can

be restored.

Hardware Upgrades

When using SnapBack, images can be restored easily to a

larger drive. SnapBack volume expansion utilities make the

additional space available to the server.

Limitations

An image-based backup has many advantages over file-

based systems. The hardware basis for the image does

create some limitations. Limitations inherent in the

SnapBack method are as follows:

• Disk and tape drives must be physically connected to the

server. SnapBack won’t use devices attached to other

servers. The Console program can run on any workstation

or connected server.

• The backup image is of the entire physical drive space, not

the space actually used by files. Even if space isn’t actually

in use, the tapes must have enough capacity to store the

entire physical drive image.

• Backup images must include entire physical hard drives.

Backup of individual partitions, directories, or files is not

supported.
