Magnetic tape backup has existed in various forms since the 1950s and is a seemingly inexpensive option.
However, with many world class CIOs moving away from tape-based backup and recovery solutions, you may want to consider their reasons for doing so:
Poor backup performance:-
- Tape systems have difficulty meeting shrinking backup windows.
- Not conducive to the remote and off-site user requirements.
- Daily and weekly incremental backups exceed the allotted time windows.
- Recovery from physical tape is cumbersome.
Lengthy recovery time:-
- Difficult to recover in a “user” environment.
- Recovery of business-critical data and applications from tape can take many hours, if not days.
- Ironically, the “best practice” of using off-site tape repositories adds to recovery time.
Increased operational and capital costs:-
- Tape deployments are costly and cumbersome to maintain.
- Adding capacity to existing tape libraries and upgrading tape drive technology to non-compatible, higher-capacity media is costly.
- Ongoing service, support and warranty is high, especially for aging tape systems.
The risk of defective, lost or misplaced tapes:-
- Shipping tape cartridges to off-site repositories exposes firms to security breaches and risks due to loss.
- Defective media can result in risking unrecoverable data.
- IT organisations must invest in tape encryption and key management systems to alleviate security risks, which adds cost and complexity.
- The “human element” involved when handling tape adds to risk of data loss and increases operational costs.
Poor storage efficiency:-
- Explosion in the growth of redundant data using tape back up – cannot easily use data de-duplication techniques.
- Tape-based compression is typically only 2:1 resulting in many sets of media – typically 1 TB of data needs 25 TB of media, using the generation tape archiving concept.
- Need to move to another media type to gain additional capacity.
- Tape is not always read or write compatible.
With some business continuity experts quoting a 42 – 71% chance of backup failure when using magnetic tapes, it may well be time to investigate what your choices are.
