![]() Why Google Vault is not a Backup Option!.More information can be found in our blog posts: Its restore process and capability is cumbersome and slow. IT managers who attempt to make use of Google Vault for backup & recovery instead of a 3rd party backup solution, find it will not function as a true primary data replacement solution. True backup & restore solutions are setup to maintain the integrity of your business data by continuously replicating a version, which can be used to replace the primary data if and when it is needed, in instances of Malware, malicious deletion, accidental, and or simply software error. Its paramount to understand and differentiate Google Vault from a backup solution, simply because its primary function is to archive and hold data so that it can be found going forward. s2-v6si1703771plr.Plainly put, G Suite – Google Vault is not a backup solution, even if there are methods to use it in order to restore lost data, in some particular situations.
