What is VMware VDR?

VMware Data Recovery (VDR) as a backup solution.

What is a VDR backup?

VDR is an image-level backup solution that’s available in the Essentials Plus bundle and vSphere Advanced editions of vSphere 4.1. VDR is intended to be the replacement for the now-deprecated VMware Consolidated Backup tool that was available in previous versions.

What is VDP VMware?

VDP is a robust, simple-to-deploy, disk-based backup and recovery solution. VDP is fully integrated with VMware vCenter Server and the VMware vSphere Web Client. VDP enables centralized and efficient management of backup jobs while storing backups in deduplicated destination storage.

What is VMware data recovery?

Data Recovery manages existing backups, removing backups as they become older. It also supports deduplication to remove redundant data. Data Recovery is built on the VMware vStorage API for Data Protection. It is integrated with VMware vCenter Server, allowing you to centralize the scheduling of backup jobs.

What is the purpose of VDR?

The primary purpose of a voyage data recorder (VDR) or a simplified voyage data recorder (S-VDR) is to maintain a store of information, in a secure and retrievable form, concerning the position, movement, physical status, command and control of a vessel over the period leading up to and following an incident.

Is vSphere replication synchronous or asynchronous?

asynchronous
vSphere Replication is a hypervisor-based, asynchronous replication solution for vSphere, enabling disaster recovery and data protection for all virtual machines in your environment.

What is the main components of VDR?

MAIN COMPONENTS OF VDR:

  • DATA MANAGEMENT UNIT (OR DATA COLLECTION UNIT)
  • AUDIO MODULE.
  • FINAL RECORDING MODULE.
  • REMOTE ALARM MODULE.
  • REPLAY STATION.
  • RESERVE SOURCE OF POWER.

What is the VMware vSphere™ on NFS?

The capabilities of VMware vSphere™ on NFS are very similar to the VMware vSphere™ on block-based storage. VMware offers support for almost all features and functions on NFS—as it does for vSphere on SAN. This paper provides an overview of the considerations and best practices for deployment of VMware vSphere on NFS based storage.

What are the best practices for VMware NFS and iSCSI?

To address the security concerns and provide optimal performance, VMware provides the following best practices: To isolate storage traffic from other networking traffic, it is considered best practice to use either dedicated switches or VLANs for your NFS and iSCSI ESX server traffic. The minimum NIC speed should be 1GbE.

What are the lock-related settings for VMware NFS v3?

Similar to heartbeat, the lock related settings for NFS v3 are NFS.DiskFileLockUpdateFreq, NFS.LockUpdateTimeout & NFS.LockRenewMaxFailureNumber and can be discussed together. To begin, the first thing to mention is that VMware isn’t using the Network Lock Manager (NLM) protocol for NFS locking.

Can I do storage vmotions on NFS datamovers?

All Storage vMotions on NFS datamovers will be done by the software datamover. The only other considerations with Storage vMotion are relevant to both block & NAS, namely the configuration maximums.
