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 more information on backup properties, see Viewing Backup Properties. In the properties of the backup created with encryption, you may also see that the backup size (the Backup Size column) is larger than the original VM size (the Original Size column). For more information 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.
