Azure File Sync

Question

Hi, One of customer is looking to implement Azure Files solution with File Sync (on-premise). As understood, Azure File Sync job is initiated to replicate the data changes every 24 hours once in a day. Customer wants to know whether this file sync operation shall perform List and Read Operations, every day when sync happens. As there is a substantial size of data which they are looking to migrate & store in the Azure Files storage, need to understand the cost implication of the List and Read operation during File Sync operation. Appreciate your quick response and support. Thanks Pranav

Hi Pranav, When using Azure File Sync to replicate data changes between an on-premise file server and Azure Files storage, the synchronization job will typically perform both List and Read operations every time it runs. These operations are required to identify the files and directories that need to be synchronized and read the content of the files that have changed since the last synchronization. The frequency of synchronization can be adjusted to better suit your needs, so it doesn't have to be limited to running once a day. However, it's important to note that List and Read operations can incur costs. While the costs are generally low, they can accumulate over time, especially when synchronizing a lot of data. You can minimize the costs of these operations by optimizing the synchronization job settings, such as using filters to limit the scope of the synchronization job to specific directories or file types, or by excluding files or directories that don't need to be synchronized. Overall, while the List and Read operations are necessary for Azure File Sync to function properly, you can control the frequency and optimize the synchronization job settings to reduce costs. I hope this helps?
