Limitations for Veeam Cloud Connect Backup

In this article

    Veeam Backup & Replication has the following limitations for cloud repository usage:

    Backup, Backup Copy and Restore

    1. Veeam Backup & Replication does not support backup copy jobs if the cloud repository is used as a source backup repository. The backup copy job must use a backup repository configured locally on the tenant side as a source one.
    2. Transaction log backup is not supported for backup jobs targeted at the cloud repository. You can back up transaction logs only with backup copy jobs in the immediate copy mode.
    3. Instant VM Recovery, multi-OS file-level restore, restore to Microsoft Azure, Amazon EC2 and Nutanix AHV from backups in the cloud repository are not supported.

    Limitations for Veeam Cloud Connect BackupNote

    Veeam Cloud Connect does not support NAS backup.

    File Operations

    Tenants can manually copy backup files to and from the cloud repository using the Files view in the Veeam Backup & Replication console. Scheduled file copy jobs are not supported.

    Scale-Out Backup Repositories Used as Cloud Repositories

    1. The SP cannot expose a scale-out backup repository as a cloud repository if unlimited number of concurrent tasks is specified for at least one extent added to this scale-out backup repository.
    2. Tenants cannot use the Files view in the Veeam Backup & Replication console to copy backup files to and from a scale-out backup repository exposed as a cloud repository. Such cloud repositories are displayed in the tenant Veeam Backup & Replication console in the read-only mode.

    Deduplicating Storage Appliances Used as Cloud Repositories

    It is not recommended to use deduplicating storage appliances as cloud repositories. To protect VM data that is backed up to the cloud repository, tenants are likely to use data encryption. For deduplicating storage appliances, encrypted data blocks appear as different though they may contain duplicate data. Thus, deduplicating storage appliances will not provide the expected deduplication ratio. To learn more, see the Data Encryption section in the Veeam Backup & Replication User Guide.

    If the SP uses a deduplicating storage appliance as a cloud repository, the SP must consider the following limitations.

    Dell EMC Data Domain

    The length of forward incremental and forever forward incremental backup chains that contain one full backup and a set of subsequent incremental backups cannot be greater than 60 restore points. To overcome this limitation, the tenant can do the following:

    • For backup jobs, the tenant can schedule full backups (active or synthetic) to split the backup chain into shorter series. For example, to perform backups at 30-minute intervals, 24 hours a day, the tenant must schedule synthetic full backups every day. In this scenario, intervals immediately after midnight may be skipped due to duration of synthetic processing.
    • For backup copy jobs, the tenant can specify the necessary number of restore points in the backup copy job settings. The number of restore points in the backup chain must be less than 60.

    If the SP plans to use Dell EMC Data Domain as a cloud repository, it is strongly recommended that the SP informs tenants about limitations for the backup chain length.

    HPE StoreOnce

    Veeam Backup & Replication does not support usage of HPE StoreOnce deduplicating storage appliances as cloud repositories.

    If the SP plans to use a scale-out backup repository as a cloud repository, he or she should consider the following limitations:

    1. The SP cannot add an HPE StoreOnce appliance as an extent to a scale-out repository that is used as a cloud repository.
    2. The SP cannot use a scale-out backup repository as a cloud repository if an HPE StoreOnce appliance is added as an extent to this scale-out backup repository.

    I want to report a typo

    There is a misspelling right here:

     

    I want to let the Veeam Documentation Team know about that.
