Veeam Community discussions and solutions for: Direct transfer VS Wan accelerator transfer for BCJ of Veeam Backup & Replication.

Consider that the savings rate (18.5x) displayed in the GUI is based on Processed data ("re-hydrated" data blocks). In the example above, 283 MB would have been transferred over the WAN link in Direct Transfer mode, while only 72.8 MB were …

Veeam Community discussions and solutions for: Do I need WAN ... compression is now about 5 x higher after WAN acceleration 24x Vs 5x the ...

Mar 04, 2021 · The Direct SAN access transport mode is recommended for VMs whose disks are located on shared VMFS SAN LUNs that are connected to ESXi hosts over FC, FCoE, iSCSI, and on shared SAS storage. In the Direct SAN access transport mode, Veeam Backup & Replication leverages VMware VADP to transport VM data directly from and to FC, FCoE and iSCSI ...

When configuring backup copy or replication jobs, tenants can choose to exchange data over a direct channel or communicate with the cloud ...

May 25, 2021 · The size of VMs to be processed is 2 TB. In this case, the needed amount of free disk space for the global cache and digests on the target WAN accelerator is: 4*100 GB + 40 GB = 440 GB. Note. For more information and recommendations on WAN accelerator cache sizing, see the Veeam KB1877 article.

25.05.2021 · Source WAN Accelerator When you run a remote job over WAN accelerators, Veeam Backup & Replication analyses data blocks going to target and calculates digests for these data blocks. Digests data is stored on the source WAN accelerator, in the VeeamWAN folder on the disk that you select when you configure the WAN accelerator.

Aug 18, 2021 · WAN accelerators are responsible for global data caching and data deduplication. Technically, WAN accelerators add a new layer in the backup infrastructure — between Veeam Data Movers on the source side and the Veeam Data Mover on the target side. To enable WAN acceleration and data deduplication technologies, you must deploy a pair of WAN ...

To better understand the difference between direct data transfer and WAN accelerated mode, examine the Read and Transferred values: Read — amount of data read from the production storage prior to applying any compression and deduplication. This is the amount of data that will be optimized by the WAN accelerator.

[For backup copy job] Veeam Backup & Replication decompresses the backup file to analyze its content. The Veeam WAN Accelerator Service on the source WAN ...

High bandwidth mode puts more load on the source WAN. Would I be better off doing direct so that data dedup comes into play? Data is deduped ...

WAN Acceleration Primary job mode affects the performance of backup copy job . Backup copy job works in forever incremental mode, transferring only the differences between previous and current job cycles to the target repository, no matter what type of the backup file is in the primary repository (Full or Incremental).

However, some users choose to use WAN acceleration on much faster links in order to optimize bandwidth consumption of a shared WAN link. If bandwidth ...

Customers with no specific needs for bandwidth usage, or backup execution time, can also use direct connection with low bandwidth. Low or High Mode? The main ...

Starting with v10 Veeam Backup and Replication supports two operational modes of WAN accelerators: Low bandwidth mode for the links with less than 100 Mbps throughput and High bandwidth mode, supporting links with up to 1 Gbps throughput. The operational mode can be controlled in WAN accelerator properties.

13.07.2018 · To isolate, start by configuring the backup copy/replication job to use the direct transport method temporarily disabling WAN acceleration. If the job works after disabling WAN acceleration, the problem is with the WAN accelerator cache and creating a new volume/rebuilding the WAN accelerator cache may be the next step.

25.09.2018 · Veeam's WAN accelerator doesn't do task concurrently as far as I know, so that's why you're seeing this difference. You can either spin up more source WAN Accelerators, or just do it direct. Your connection should be fast enough to support direct, though you may need to seed the backup copy. Re: Direct transfer VS Wan accelerator transfer for BCJ

Oct 21, 2011 · Re: Direct transfer VS Wan accelerator transfer for BCJ. Veeam's WAN accelerator doesn't do task concurrently as far as I know, so that's why you're seeing this difference.

Dec 22, 2021 · WAN accelerator (source and target) Backup repository (source and target) TCP. 2500 to 3300 1. Default range of ports used as data transmission channels. For every TCP connection that a job uses, one port from this range is selected dynamically. WAN accelerator. WAN accelerator. TCP. 6164. Controlling port for RPC calls. TCP. 6165

Wan Acceleration is designed to optimize high latency or low bandwidth links ... Link more than 50Mb/s - WAN will not be fully utilized, using direct mode ...

01.09.2020 · The Veeam WAN Accelerator Service compares the created digests with the digests that have been previously stored to the VeeamWAN folder on the source WAN accelerator. If duplicate data blocks are found, the actual data block in the backup file is not copied over WAN.

18.08.2021 · WAN accelerators are responsible for global data caching and data deduplication. Technically, WAN accelerators add a new layer in the backup infrastructure — between Veeam Data Movers on the source side and the Veeam Data Mover on the target side. To enable WAN acceleration and data deduplication technologies, you must deploy a pair of WAN ...

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 ...

24.10.2015 · The description from Veeam shows that the WAN accelerations speeds things better over slower networks or networks that have higher latency, but moves the process to the server and is more disk intensive.
