Instance Consumption for NAS Backup Jobs

In this article

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

    • Veeam Backup & Replication rounds the protected amount of data for each file share down to 500 GB.
    • One license instance covers 500 GB of the protected amount of data.
    • To calculate the total number of license instances to consume for NAS backup support, Veeam Backup & Replication sums the protected amount within all file share backup jobs, rounds this amount down to 500 GB and calculates the number of instances required for the protection of all file shares.
    • Veeam Backup & Replication calculates the protected amount of data for each NAS during every run of the file share backup job that protects file shares on this NAS and keeps the result for 30 days. To calculate the number of license instances to consume for the file share protection, Veeam Backup & Replication takes the largest protected amount of data on file shares within the last 30 days.

    If the size of the file share reduces and does not increase or the file share is removed from the file share backup job, 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.

    • If the file share is protected by more than one backup job, to calculate the size of the protected amount of data Veeam Backup & Replication sums the size of the file share data protected by each job.

    Examples

    Case 1

    If the protected amount of data for the file share is 499 GB or less, Veeam Backup & Replication rounds it down to 0 GB. In this case, protection of this file share will not consume license instances.

    If the protected amount of data for the file share is 590 GB or 990 GB, Veeam Backup & Replication rounds it down to 500 GB. In this case, protection of this file share will consume 1 license instance.

    Case 2

    If the protected amount of data for the file 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 3

    You have two file shares File Share 1 (990 GB) and File Share 2 (990 GB) protected by file share backup jobs. In this case, Veeam Backup & Replication sums the protected amount, rounds it down to 500 GB and calculates the number of license instances required to protect them:

    990 GB + 990 GB = 1980 GB ~ 1500 GB - the total protected amount of data consumes 3 license instances.

    Case 4

    You have a file share with the protected amount of data 1490 GB. Veeam Backup & Replication runs the file share backup job and after rounding down the amount, it calculates that it will consume 2 license instances for protecting this file share:

    1490 GB ~ 1000 GB = 2 license instances

    Two days later, the size of the file 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 ~ 1500 GB = 3 license instances

    Two days later, the size of the file 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 file share starts consuming 2 instances again.

    Case 5

    You have a file share (100 GB) protected by 2 file share backup jobs (1 and 2). During the 1st run of job 1, Veeam Backup & Replication rounds the protected amount down to 500 GB (0 GB) and calculates that the protection of this file share with job 1 does not consume license instances. After that the file share size increases to 270 GB. During the 1st run of job 2 which is scheduled after the increase of the file share, Veeam Backup & Replication calculates amount of data protected by all file share backup jobs protecting this file share:

    100 GB (run 1 of job 1) + 270 GB (run 1 of job 2) = 370 GB

    Veeam Backup & Replication rounds the protected amount down to 500 GB (0 GB) and calculates that the protection of this file share with backup job 1 and 2 does not consume license instances. After that the file share size remains 270 GB. During the 2nd run of job 1, Veeam Backup & Replication calculates amount of data protected by all file share backup jobs protecting this file share:

    270 GB (run 2 of job 1) + 270 GB (run 1 of job 2) = 540 GB

    Veeam Backup & Replication rounds the protected amount down to 500 GB (500 GB) and calculates that the protection of this file share with backup job 1 and 2 now consumes 1 license instance.
