Veeam WAN Accelerator . By combining multiple technologies such as network compression, multi-threading, dynamic TCP window size, advanced deduplication and global caching, WAN acceleration provides increased transport speed for Backup Copy and Replication jobs on low bandwidth or limited network links; or in any situation where we want to optimize the network usage, at the expense of other ...

For more information, refer to the WAN Acceleration section of the Veeam Backup & Replication User Guide. The WAN accelerator uses its own digests based on the hashes of the blocks inside a VM disk, which means that it reads data from the backup files and re-hydrating them on the fly, or it reads directly from the source VM in case of replication.

As the target WAN accelerator can handle multiple incoming streams (as described in the Many-to-One WAN Acceleration section of the User Guide), it is recommended to maintain a 4:1 ratio between the number of source WAN accelerators per target WAN accelerator. This guideline is very much dependent on the WAN link speed.

VeeamWAN\Digests. On the source WAN accelerator there are the VM disk digests that take up disk space.

WAN accelerators are optional components that can be deployed at the service provider to improve bandwidth utilization of remote backups and replicas sent by ...

01.09.2020 · The Veeam WAN Accelerator Service on the source WAN accelerator analyzes data blocks of the file to be transferred and creates a file with digests for these data blocks. The created file with digests is stored to the VeeamWAN folder on the source WAN accelerator. Veeam Backup & Replication compresses the backup file data (for backup copy) or VM ...

Veeam Backup & Replication Best Practices. ... The WAN accelerator uses its own digests based on the hashes of the blocks inside a VM disk, which means that it reads data from the backup files and re-hydrating them on the fly, or it reads directly from the source VM in case of replication.

Average throughput per target WAN accelerator: 500 Mbit/s (62.5 MB/s) Depending on the achieved data reduction rate (typically 10x), the transfer rate over the WAN link will vary. If the processing rate is 62.5 MB/s, and the data reduction rate is 10x, then it is possible to sustain 6.25 MB/s (50 Mbit/s) over the WAN link.

The I/O requirements for the source WAN accelerator spikes every time a new VM disk starts processing, so the typical I/O pattern is made of many small blocks.
