Since compression ratio is very often around 2x, with this block size, Veeam will write around 512KB or less to the repository per Veeam block. You can customize the block size during the job configuration using the storage optimization setting of the backup job.īy default, Veeam’s block size is set to local target, which is 1MB before compression. However, it is highly recommended to test this prior to deployment whenever possible.ĭuring the backup process, data blocks are processed in chunks and stored inside backup files in the backup repository. Block sizesĪs can be seen from the field, optimal value for the stripe size is often between 128KB and 256KB.
