Critical business data can be lost or corrupted by accidental or malicious activity, 3rd party app sync / automated tasks, and virus / ransomware.
#2 Online service providers do not backup client data
Data replication across datacentres and geo-regions is for internal
use only, point-in-time recovery is not available to the end customer.
#3 Recycle Bin and Archiving are not backup & recovery solutions
Services such as EOA and Google Vault support eDiscovery for litigation and regulatory compliance, they do not provide point-in-time recovery.
