- Retention and scheduling policy should be set according to your restore scenarios. E.g., if there is a dataset that will be required a year after it was deleted, then your settings should reflect it and you must be sure that this data is stored properly.
- The optimal settings are dependent on data type. You might end up with different requirements for operating system level backups, application backups and file-level backups.

- Retention policy settings can vary based on the backup storage type or class. You can store frequently required backups locally for quick access, and keep long-term archives in the cloud.
- We recommend keeping your backup chain in incremental backups within the reasonable size of 14 increments; thus, it is best to schedule a full backup once in a while.
- When choosing the optimal backup schedule, consider your business needs first. How granular should your restore timing be? Should you have the availability of monthly, weekly, daily or even hourly restore points?

- You should also take into account that backup jobs running on production systems can impact the connectivity and performance of these systems. Data uploads may eat up your bandwidth and increase I/O load on the system. Thus, try scheduling weekly backups to run during non-business hours or on weekends. As for daily backups, we recommend using bandwidth throttling to optimize the network load.
