On-Premise Backup

This most traditional of backups normally takes the form of external hard drives, tape drives, USB drives, and network attached storage (NAS) kept at your office. Typically you would perform a daily incremental backup, full weekly and a monthly backup.

Disadvantages:

• Complicated Process Data backup requires a commitment to a media rotation and a replacement plan – neither simple nor quick.
• Error-prone Inserting, rotating, labelling, storing, off-siting and finding tapes for recovery purposes all rely on manual processes which introduce errors, especially if the nominated person isn’t checking the backup.
• Time consuming Weekly full backups take time and involve large backup volumes.
• Untested and slow restores Backup media is very rarely tested and is very slow to restore.
• Inadequate storage Media is often stored on-site rather than off-site in a secure environment.
• Limited scalability Expanding data libraries is expensive and cumbersome.
• Easily damaged and hard to maintain Data on a removable storage medium can be easily lost or damaged.
• Obsolescence Modern systems could be incompatible with older media.

The main advantages of on-premise backups:

• Data readily available for quick restores With proper on-site backups, you can recover from data loss due to intentional or unintentional deletion, viruses, and hardware failure with minimal downtime
• Internet service not required Saving on costs and support.
• Low cost Cheap local storage options allow you to keep multiple copies of backup data easily.
