Incremental Backup
Incremental Backup
Incremental backups include files that
were created or changed since the last backup (that is, the last full or
incremental backup).
To achieve this, the status of each file must be
recorded either within the backup software or through the use of the
archive attribute of the files. If no previous backup was made, an
incremental backup is equivalent to a full backup.
Incremental backups
make better use of media compared to full backups. Only files that were
created or changed since the last backup are included, so less backup
space is used and less time is required.
The disadvantage is that
multiple tapes are needed to restore a set of files. The files can be
spread over all the tapes in use since the last full backup. You may
have to search several tapes to find the file you wish to restore. The
backup software can minimize this by remembering where files are
located; however a restoration may still require access to all
incremental backups.
