Archive versus
Backup and
Restore
Backup and restore applications are usually an automatically
scheduled operation aimed at protecting original data against
any kind of loss or damage.
The goal of archiving is usually to conserve online storage
space. It is more cost effective to store infrequently accessed
data on lower cost media.
Files Viewed as
Online
When applications need to read from or write to archived files,
the files appear as a single, mounted file system on the UNIX
server.
Applications can read from the files or write to the files the
same way they would read or write to a hard disk. Therefore,
the extensive storage capabilities provided by storage hardware
appear as one large file system.
Although applications view their files as being located on the
UNIX server, in reality they are stored on multiple storage
system—or even on offline storage.
