With this option selected, Veeam Agent for Microsoft Windows uses data block size of 256 KB. The WAN target option is recommended if you plan to use WAN for offsite backup.This option reduces the size of an incremental backup file because of reduced data block sizes. With this option selected, Veeam Agent for Microsoft Windows uses data block size of 512 KB. The LAN target option is recommended for backup to NAS and onsite backup.This option provides the fastest backup job performance. The SAN identifies larger blocks of data and therefore can process large amounts of data at a time. With this option selected, Veeam Agent for Microsoft Windows uses data block size of 1024 KB. The Local target option is recommended for backup to SAN, DAS or local storage.Keep in mind, however, that this storage optimization option will provide the largest size of incremental backup files. Large data blocks produce a smaller metadata table that requires less memory and CPU resources to process. With this option selected, Veeam Agent for Microsoft Windows uses data block size of 4096 KB.

The Local target (large blocks) option is recommended for backup jobs that can produce very large full backup files - larger than 16 TB.

You can choose one of the following storage optimization options: You do not need to create a new full backup to use new settings - Veeam Agent for Microsoft Windows will automatically apply the new compression level to newly created backup files.ĭepending on the type of storage you select as a backup target, Veeam Agent for Microsoft Windows uses data blocks of different size, which optimizes the size of a backup file and job performance. They will be applied to new backup files created after the settings were changed.Ĭompression settings are changed on the fly. New settings will not have any effect on previously created backup files in the backup chain. You can change data compression settings for existing backup jobs. We recommend that you use the extreme compression level only on Veeam Agent computers with modern multi-core CPUs (6 cores recommended).

Extreme compression provides the smallest size of the backup file but reduces the backup performance.

High compression level provides additional 10% compression ratio over the Optimal level at the cost of about 10x higher CPU usage.

It provides the best ratio between size of the backup file and time of the backup procedure.

Optimal is the recommended compression level.

You can select this compression level if you want to decrease the load on the CPU of the Veeam Agent computer.

Dedupe-friendly is an optimized compression level for very low CPU usage.

None compression level is recommended if you plan to store backup files on storage devices that support hardware compression and deduplication.

Veeam Agent for Microsoft Windows allows you to select one of the following compression levels: Data compression and deduplication let you decrease traffic going over the network and disk space required for storing backup files.ĭata compression decreases the size of created backups but affects duration of the backup procedure. Veeam Agent for Microsoft Windows provides mechanisms of data compression and deduplication.
