Tape Backup Strategy- Implementation

If you are wondering on how to make a backup strategy, The following guideline provide some example on how the backup strategy is implemented.

Back up all server data files including databases, Directories & files. Following your company's standardized backup procedures, back up files directly to tape or to a file server and then to tape. Never rely only on replication as your method of database backup. A damaged or accidentally changed database may replicate, and then your only recourse is to recover the database from a server backup tape.

Follow these guidelines to back up File servers:

1.       Backup all system files

2.       Backup all important users working environment data

3.       Backup all database data
