DangersÂ of Outdated Backup Solutions

Time is money and those who waste time and money will soon find themselves outÂ ofÂ business. OneÂ ofÂ the factors that can waste both your time and your money is the useÂ ofÂ outdated backup technologies. So, if the enterprise is still using outdated backup technologies, it needs to heed the dangers and risks associatedÂ withÂ it.
What are the dangersÂ ofÂ outdated backup solutions?Â WithÂ the growthÂ of dataÂ volumes, organizations have come to the realization that outdated and traditional backup strategies no longer meet theirÂ dataÂ protection, service level or cost structure requirements. A fundamentalÂ dataÂ backup paradigm shift is the demandÂ ofÂ the day! Businesses needÂ dataÂ on demand, and the dataÂ life cycle management must take into consideration this information on demand environment while definingÂ dataÂ backup protocols and technologies. Secondly, theÂ dataÂ backup solution must enable customer complyÂ withÂ the increased regulatory scrutiny governing the managementÂ of dataÂ that is archived or stored in servers for instantaneous access. Security ofÂ data, managementÂ ofÂ dataÂ and disposalÂ ofÂ dataÂ are concerns that cannot be addressed by outdatedÂ dataÂ backup solutions and therein lay the dangersÂ ofÂ using outdated backup solutions.
HistoricallyÂ dataÂ was backed upÂ withÂ an intention to prevent dataÂ loss and for disaster recovery. Large amountsÂ ofÂ dataÂ backed up into arraysÂ of tapes or disks took hours or even days to backup or restore and that came at the costÂ ofÂ lossÂ ofÂ business time. The growing globalizationÂ ofÂ economies does not permit enterprises to remain offline for days or even hours at a time. The amountÂ ofÂ dataÂ that was generated then and is being generated now is also volumetrically different and bottlenecks inÂ dataÂ backup or restore can be crippling. It follows thatÂ dataÂ backup applications must backup moreÂ dataÂ in less time.
EarlyÂ dataÂ storage methodologies requiredÂ dataÂ to be backed up into a local or a central server and local file stores were used to store almost all dataÂ ofÂ the enterprise. Access to thisÂ dataÂ was via a LAN that used common IP network protocols like NFS, FTP, CIFS.Â Backup applications made incremental copiesÂ ofÂ theÂ dataÂ directly to a local tape drive in this scenario and the network was not used for local data transfer. However, these systems are extremely vulnerable and subject to all the restrictions and limitationsÂ ofÂ the enterprise wide network. The limitations include limitations in the numberÂ ofÂ tape drives in the tape library; limitation ofÂ the numberÂ ofÂ I/O channels in a server; limitationsÂ ofÂ scalabilityÂ of backup applications and inability to keep all tape drives streaming in parallel.
ModernÂ enterprise wide backup technology allows disparate enterprise wide clients to automatically move the backupÂ dataÂ via a network to a tape drive(s) connected to a backup server, so that, automated tape libraries can backup multiple clients in parallel. Also, online backup comes in handy to automatically backup ever growingÂ data.Â DataÂ de-duplication,Â data replication,Â dataÂ mirroring and cloud backups make for redundancyÂ ofÂ data backups that can be performed during the run timeÂ ofÂ the business. This also makes for high availability and instantaneous restore while the business is in operation. Disaster recovery and business continuity are instantaneous and there is no lossÂ ofÂ time or money during the process. These systems also lower administrative costs and infrastructure costs.
In short, modernÂ dataÂ backup solutions are designed for handling large volumesÂ ofÂ dataÂ backup and restore; to lower total costÂ ofÂ ownership by maximizing storage infrastructure utilization and reducing administrative costsÂ ofÂ backup and restore operations. They make a directional effort to limit the reliance offline backup systems that makeÂ dataÂ life cycle management a nightmare and data restoration and business continuity a long drawn process.
