If you need to backup network share data, follow the guidelines below for optimal functionality.

• Multiple shares are supported.
• To ensure that backups can complete in a timely manner, do not exceed: 
  • 5 million files per network share
  • 10 million files per backup account protecting network share data
• The ESE client is compatible with the SMB3 protocol. We can backup cloud-based SMB data sources that support this protocol, such as Azure file share.
• If using cloud file shares:
  • Data will be scanned regularly, so using cloud “pay per transaction” storage is not recommended.
  • We recommended running the ESE agent on a virtual machine in the cloud, within the same region, and if possible to use a private network endpoint. This will minimise latency in communicating with the file share.
  • Data transmitted may be seen as egress data and incur bandwidth charges with the cloud provider.
