This section provides instructions to create a backup policy for NAS shares.
Creating a backup policy
Step 1: General information
In the Overview section, enter the following details, and then click Next.

Description |
Name |
Name of the backup policy that is being created |
Description |
Enter a short description of the backup policy |
Step 2: Backup Schedule information
In the Backup Schedule section, enter the following details:

Field |
Description |
Backup Frequency |
Select the days on which you want the backups to run |
Start at (Server Time zone) |
Enter a short description of the backup policy |
Backup Window(Hrs) |
The duration after which you want backup operations to stop.
For example, if you set Start at to 9 AM and you set the Backup Window to 2 hours, backups of your NAS shares start at 9 AM and stop at 11 AM, even if they do not complete. |
Max. Bandwidth (Mbps) |
The maximum bandwidth that the NAS proxy can consume while backing up data to Phoenix.
A scheduled backup job consumes the assigned bandwidth. A manually triggered backup job consumes the available bandwidth on your network.
|
Add Schedule: Use it to create more schedules. Click Add Schedule as many times as the number of schedules you want to create.
Ignore backup window for the first backup: Ignore the backup window for the first backup job. You can disable this option to enforce the backup window for the first backup job. The first backup can exceed the backup window because it needs to scan a large number of files. We recommend keeping this option enabled to ensure that the first backup is successful.
The Remove icon is displayed when you have added more than one schedule.

In the Advanced Settings section, enter the following details, and click Next.

Enable Smart Scan |
For NAS share backups, you can enable Smart Scan if you have a lot of files that haven’t changed recently. Skipping these files makes incremental backups faster.
|
Smart Scan Settings
You can select the following settings if Smart Scan is enabled. Smart scans follow the backup schedule for the policy.
|
Skip Scanning ACLs or permissions for unmodified files |
Select this option to skip scanning the Access Control Lists or permissions of files that have not changed recently. |
Only scan files created/modified in the last X months |
Only scan files that were created or modified in the last <number of > months. You can enter 3, 6, 9, or 12 months for the duration. All files that are older than the specified duration are skipped from Smart Scans. |
Full Scan Schedule |
Even if you enable smart scan, you can still run a full scan. You can choose to run a full scan every 24 weeks or less. We recommend that you run a full scan every four weeks. Also, specify the preferred day, time, duration, and bandwidth.
Note: If you change the Backup Content setting under the backup set, the subsequent scan is a full scan.
|
Step 3: Retention information
In the Retention tab, enter the duration for which the daily, monthly, weekly and yearly snapshots should be retained and click Next.

Notes: Any changes that you make to the existing retention policies will be applied to all the new as well as the existing snapshots.
Enable Long Term Retention (LTR)
For backup sets that need to be retained for a year or longer, you can enable Long Term Retention. Snapshots older than 15 days are moved to the cold tier. Data stored in the cold tier incurs a 30% lower fee. For more information, see About Long Term Retention, and Enabling Long Term Retention.
