# Using Veeam with Leviia

| Objective

This documentation aims to show you how to optimize the performance of your Veeam backups with Leviia.

| Prerequisites

*  [Having created an identifier on the Leviia dashboard](https://wiki.leviia.com/en/article/create-object-storage-identifier-in-your-leviia-dashboard-1as7ljn/)
*  [Having created a bucket on the Leviia dashboard](https://wiki.leviia.com/en/article/create-a-bucket-on-your-leviia-dashboard-h47vp5/)
*  [Having downloaded Veeam Backup & Replication V12](https://www.veeam.com/products/veeam-data-platform/backup-recovery.html)
*  [Having created a backup repository on Veeam](https://wiki.leviia.com/en/article/veeam-backup-replication-v12-create-your-leviia-repository-15kzmfb/)

| Enable object locking on your bucket

If you want to enable immutability on your bucket, it must be configured according to [this procedure](https://wiki.leviia.com/en/article/leviia-configuration-for-immutability-with-veeam-backup-and-replication-1kr5efy/) in order to make it compatible with Veeam.

| Create multiple Leviia identifiers

Our anti-abuse system works by identifier, we recommend you to [create several](https://wiki.leviia.com/en/article/create-object-storage-identifier-in-your-leviia-dashboard-1as7ljn/) so as not to have all your buckets associated with the same identifier.

| Distribute your backups across multiple buckets

Multiple backup jobs should not be performed on the same bucket. It is important to always associate a backup job with a different bucket.

| Increase block size to 4MB

It is possible to increase the block size to 4MB. To do this, go to the properties of your backup jobs.
