Veeam Backup & Replication uses Veeam Data Movers to deduplicate VM data: However, note that data deduplication may decrease job performance.

BACKUP SOFTWARE FOR WINDOWS 10 WITHOUT COMPRESSION FREE

We recommend you enable data deduplication if your backup jobs contain several VMs that have a lot of free space on their logical disks or VMs that have similar data blocks - for example, VMs that were created from the same template. With data deduplication enabled, Veeam Backup & Replication does not store to the resulting file identical data blocks and space that has been pre-allocated but not used. All subsequent backup files in the backup chain will also use the new compression level.ĭata deduplication decreases the size of files. Veeam Backup & Replication will retrieve data for the whole VM image from the production infrastructure and compress it at the new compression level.

BACKUP SOFTWARE FOR WINDOWS 10 WITHOUT COMPRESSION FULL

If you want the newly created backup file to contain data blocks compressed at one level, you can create an active full backup. The same behavior applies to synthetic full backups: synthetic full backups created after the compression level change will contain a mixture of data blocks compressed at different levels. As a result, the full backup file will contain a mixture of data blocks: data blocks compressed at the Optimal level and data blocks compressed at the High level. In the reverse incremental backup chains, the full backup file is rebuilt with every job session to include new data blocks.

After several job sessions, you change the compression level to High. For example, you have a backup job that uses the reverse incremental backup method and the Optimal level of compression. However, if you use the reverse incremental backup method, the newly created backup files will contain a mixture of data blocks compressed at different levels. Previously created backup files will not be affected. Veeam Backup & Replication will automatically apply the new compression level to the newly created backup files after you save the settings. After you change the settings, you will not need to create new full backups to use new settings. You can change data compression settings for existing jobs. For details on job statistics, see Viewing Real-Time Statistics. Therefore, in the job statistics, you may observe a higher amount of transferred data (the Transferred counter) as compared to a job for which encryption is disabled. If encryption is enabled for a job and the Decompress backup data blocks before storing check box is selected in the settings of the target backup repository, Veeam Backup & Replication does not compress VM data. Select this level to use compression settings of the copied backup files.

Auto is the recommended compression level for backup copy jobs.

We recommend that you run backup proxies on computers with modern multi-core CPUs (6 cores recommended) if you intend to use the extreme compression level.

Extreme compression provides the smallest size of the file but reduces the 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 file and time of the procedure.

Optimal is the recommended compression level.

Select this compression level if you want to decrease the load on the backup proxy.

Dedupe-friendly is an optimized compression level for very low CPU usage.None compression level is recommended if you plan to store backup files and VM replica files on storage devices that support hardware compression and deduplication.Veeam Backup & Replication 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 and VM replica files.ĭata compression decreases the size of created files but affects duration of the backup or replication procedure. Veeam Backup & Replication provides mechanisms of data compression and deduplication.
