Backup prerequisites

Ensure that you meet the following backup prerequisites:

  • You have installed the correct versions of Avamar, hotfixes, and VCF by reviewing the compatibility information at E-Lab Navigator.
  • You have discovered any external server that uses SFTP or another supported protocol, and is used in a file-based backup, as a client on the Avamar server.
  • You have added the vCenter Server that protects the VxRail and VCF virtual machines to the Avamar server.
  • Policies with appropriate data sets are present on the Avamar server. Policies enable you to protect the VxRail and VCF components.
    • At least one policy with data sets that support file system protection is present.
    • At least one policy with data sets that support VMware virtual machine protection is present.
    • A policy with data sets that supports file system protection, and is created for external (SFTP) server backups must have the Select Files and/or Folders option selected under the Source Data section of Dataset.

      The option enables you to select required folder or files instead of an entire file system.

  • You have set Avamar and the vCenter, SDDC, and NSX-T managers to the same time zone, and synchronized their clocks.
  • Avamar and VCF must not contain the backup schedules that back up the same assets at the same time.
  • You have configured policies to ensure that they meet the quiescing and backup job requirements that VMware outlines. VMware Quiescing Recommendations provides information.
  • You use only Unix and Windows file system external backup servers as Avamar clients.
  • Proxies are present.
  • A backup folder path that an external server uses for a file-based backup is present.
  • The user credentials that the backup script uses must resolve to the accounts with the required permissions to access the relevant resources.
  • Ensure that the required ports are open in the firewall configuration.

    For example, if you use an SFTP server, the port 22 on the SFTP server must be open to communicate with the vCenter Servers, SDDC Manager, and NSX-T Managers.
