Instance Consumption for NAS Backup Jobs

In this article

    For NAS backup, there are the following peculiarities in calculating the number of license instances to consume:

    • One license instance covers 500 GB of the protected amount of data.
    • Veeam Backup & Replication rounds the protected amount of data for each NAS share down to 500 GB.
    • The first 500 GB in the protected amount of data does not consume license instances. Veeam Backup & Replication deducts this 500 GB from the protected amount of data to calculate what amount of data consumes license instances.
    • The free protected amount is calculated separately for each of the file shares added in the inventory.

    Note

    If you have added a server, where several file shares reside, as a root folder, the free protected amount is calculated for the whole server.

    • If the NAS share is protected by more than one backup job, to calculate the size of the protected amount of data Veeam Backup & Replication multiplies the size of the NAS share source by the number of jobs.
    • To calculate the total number of license instances to consume for NAS backup support, Veeam Backup & Replication calculates the number of instances required for the protection of each separate NAS share and then sums these numbers.
    • Veeam Backup & Replication calculates the protected amount of data for each NAS during every NAS backup job run and keeps the result for 30 days. To calculate the number of license instances to consume for the NAS share protection, Veeam Backup & Replication takes the largest protected amount of data within the last 30 days.

    If the size of the NAS share reduces and does not increase, after 30 days Veeam Backup & Replication recalculates the protected amount of data and automatically revokes the excessively consumed license instances.You can manually revoke the licenses without waiting for 30 days, as described in Revoking License. During the next NAS backup job run, Veeam Backup & Replication will recalculate the license instance consumption as of the current date.

    Examples

    Case 1

    If the protected amount of data for the NAS share is 1000 GB after rounding, Veeam Backup & Replication divides this amount by 500 GB to calculate the number of instances to consume:

    1000 GB / 500 GB = 2 license instances

    Case 2

    If the protected amount of data for the NAS share is 590 GB or 990 GB, Veeam Backup & Replication rounds it down to 500 GB.

    Case 3

    If the protected amount of data for the NAS share is 540 GB, Veeam Backup & Replication deducts 500 GB from this amount:

    540 GB - 500 GB = 40 GB

    Case 4

    You have a single NAS device, but you add two of its shared folders to the inventory as separate file shares: File Share 1 (540 GB) and File Share 2 (750 GB). In this case, Veeam Backup & Replication deducts free 500 GB from the protected amount of data for each of these shared folders separately:

    File share 1: 540 GB - 500 GB = 40 GB

    File share 2: 750 GB - 500 GB = 250 GB

    Case 5

    You have a single NAS device with 2 NFS file shares residing on it: File Share 1 (540 GB) and File Share 2 (750 GB). You have added the root server folder of this NAS device as an NFS file share to the infrastructure. In this case, Veeam Backup & Replication deducts free 500 GB from the protected amount of data for the whole server:

    Protected amount = (540 GB + 750 GB) - 500 GB = 790 GB

    Case 6

    If a 270 GB NAS share is protected by two NAS backup jobs, the protected amount of data is multiplied by two:

    270 GB x 2 = 540 GB

    Case 7

    You have two NAS shares: File Share 1 (540 GB) and File Share 2 (1550 GB). In this case, Veeam Backup & Replication separately calculates the number of license instances required to protect each NAS share and then sums them up:

    File share 1: 540 GB - 500 GB = 40 GB - this file share is covered by 1 license instance

    File share 2: 1550 GB - 500 GB = 1050 GB - this file share is covered by 2 license instances

    In total, 3 license instances are used to protect these 2 file shares.

    Case 8

    You have a NAS share with the protected amount of data 1490 GB. Veeam Backup & Replication runs the file share backup job and after deducting the free 500 GB and rounding down the amount, it calculates that it will consume one license instance for protecting this NAS share:

    1490 GB - 500 GB = 990 GB ~ 500 GB = 1 license instance

    Two days later, the size of the NAS share increases to 1510 GB. Veeam Backup & Replication runs the file share backup job and recalculates the number of license instances to consume based on the increased size of the NAS share:

    1510 GB - 500 GB = 1010 GB ~ 1000 GB = 2 license instances

    Two days later, the size of the NAS share decreases back to 1490 GB and does not increase any more. Although the protected amount of data decreases, for the next 30 days Veeam Backup & Replication uses value 1510 GB as a basis to calculate the consumption of license instances.

    30 days later, Veeam Backup & Replication runs the file share backup job and recalculates the number of instances to consume taking into account that the largest protected amount of data within the last 30 days is 1490 GB. After that, protection of the NAS share starts consuming 1 instance again.
