With the exponential growth of data in recent years, we have seen that the necessity of data preservation is driving organizations to create new processes and procedures. At the same time, third-party vendors are developing new technologies that allow organizations to preserve data for eDiscovery, legal hold, governance and compliance purposes.
With legal hold, for example, you can preserve user backup data and avoid data deletion. Wikipedia describes this as:
“A legal hold is a process that an organization uses to preserve all forms of potentially relevant information when litigation is pending or reasonably anticipated.”
In this process, Electronically Stored Information (ESI) to be collected and preserved can be broadly classified into:
- Custodian data: email, personal storage on hardware devices or cloud accounts, social networking sites, tablets, smartphones
- Non-Custodian data: databases, cloud storage, shared storage
