Data generated by your firm exists in the electronic dimension. As the data ages, it reduces in value, ceases to be actively accessed and becomes ripe for archiving. Archived data is data that needs to be retained in the data repository for historical or legal reasons and not for operational reasons.
The purpose of archiving data is to reduce overheads. Overheads are associated unnecessary access to large volumes of closed/least value transactional data that add no value to the current operations of your firm. Identification and archiving of such data helps the firm leverage the electronic dimension efficiently.
Cloud backup service providers leverage standard application archiving logic with customization support to archive data. The basic application archives the data to a separate table space or database. Customizations leverages native application archiving routines and extend, replace or rebuild application archiving logic to suit specific business practices. The flexible architecture allows you select the “best fit” option for your needs.
The archive itself maintains referential integrity, promotes transparency and supports end-user merges and archive view. Some service providers commission rich tool-support such as integrated patch synchronization, space reclamation and single console operation. Meta data generated for the archived data is designed for reuse and extends the value of the archiving investment for enterprise search capabilities. It further helps maintain compliance.
New cloud based archiving technologies have integrated tiered archiving into recovery and data protection solutions. A very simple tiered archiving model creates second or third tier archives off the backup copies of the file servers or mail boxes stored in the original backup tier. This has the effect of reducing server loads and bandwidth needs of small and medium enterprises. The original backup tier is treated as the first tier and data is moved on the basis of time stamps from tier to tier. A stub file may be retained in the first tier to indicate the new storage location of the archived files. The archiving tiers may consist of shelves of disk drives or SSDs within the array architecture itself or tiers on other platforms. Tiering needs can be very customer specific and need specific.
Modern day cloud based tiered storage architectures are more sophisticated and are often based on an understanding of the data or file system that the data will ultimately reside in.
In consistency with the philosophy of outsourcing data storage, users demand the freedom to switch providers or store across platforms or manage file based systems across different tiers of storage from different manufacturers.
