File Follies

Pulling individual files isn’t necessarily a walk in the park

either. Backup programs use a proprietary tape format.

Browsing for a file or opening a tape-based file just isn’t

possible. In the past, a user could tell an administrator the

name of an archived file to be restored. Today, a user

document may be dynamically linked to dozens of files in

elaborate directory trees (restored any Web pages or Active

X documents lately?).

INTRO

The Trouble with Files

Current backup system problems are essentially problems

with files. Backups based on files run under server control.

The file server controls security, access, and processing of

files. Since files require special handling in order to be

shared, special software is required for open files. Since

files are protected by security systems, backup software

must have complete administrator access to the file system.

Should a server fail, the server, backup software, and basic

security must be recreated before component files can be

restored. Backup software files are recorded in proprietary

formats that only the creating software can decipher; hence,

individual file recovery must be via backup software only.

Resourceful administrators and enterprising vendors have

developed solutions to these problems. These solutions,

however, are sometimes expensive, usually complicated,

and almost never transparent to the network users.
