Phoenix offers you a viable, cost-effective way of storing, managing, archiving, and recovering your data on NAS devices. The key highlights of the Phoenix support for NAS devices are as follows:
- Scale-out NAS agent that allows parallel and performant backups for large NAS deployments.
Smart scan approach, including machine learning through metadata analysis that identifies data that has changed for backup versus repeatedly backing up all data regardless if it has changed or not. By focusing on backing up only the new or changed data, backup cycles are dramatically shortened.
Native data format and vendor-agnostic approach that enables device migration and data intelligence use cases.
The Phoenix components of NAS shares are:
- Phoenix Cloud: This is the server component of Phoenix that authenticates and authorizes incoming backup and restore requests from the NAS proxy. The NAS proxy is installed on a separate Windows or Linux server and redirects the requests to the Phoenix storage.
- Phoenix Management Console: The Phoenix Management Console is a web-based, unified console that provides complete visibility and understanding of the health status of the NAS devices and its shares that you manage, wherever those NAS devices reside. You can globally view all of the NAS devices located in your storage infrastructure and configure NAS shares for backup, recovery, and archival of the data. The console provides Phoenix administrators with an ability to:
- Register and configure NAS devices and shares for backup in the server infrastructure of the organization.
- Control Phoenix activities by defining backup content, backup policy, retention period, and more.
- Monitor backup and recovery jobs, activities, and reports.
- NAS proxy: The NAS proxy is the Phoenix Agent installed on a Windows or Linux server, which handles the backup and restore requests from the NAS shares. You need to install and activate the NAS proxy to establish its connectivity with Phoenix. The link between Phoenix and a NAS device is established when you map an activated NAS proxy to a NAS device. You can map multiple proxies to a device and can also attach it to multiple backup sets.
- Phoenix CloudCache: The Phoenix CloudCache is a dedicated server that temporarily stores backup and restore data from the NAS shares. At periodic intervals, Phoenix CloudCache synchronizes this data to the Phoenix Cloud and reduces the bandwidth consumption within your infrastructure.
Phoenix provides the following backup capabilities for NAS shares:
Auto-discovery of NAS shares
Phoenix initiates an automatic discovery of shares on the NAS device as soon as you add the NAS device. You can also use the Discover Shares option to run a share auto-discovery on demand. Share auto-discovery is particularly useful when the NAS device has a large number of shares and manual addition one by one is cumbersome. You can still add shares manually if required. The share auto-discovery process runs at 01:30 AM UTC every 24 hours. The frequency or time of NAS share auto-discovery cannot be altered.
The following table explains the mapping required between a NAS proxy and NAS device to discover SMB and NFS shares.
|Share type on the NAS device||NAS device is mapped to||Shares discovered|
|CIFS/SMB||Windows NAS proxy||CIFS/SMB|
|NFS||Linux NAS proxy||NFS|
|CIFS/SMB and NFS||Windows NAS proxy||CIFS/SMB|
|CIFS/SMB and NFS||Linux NAS proxy||NFS|
|CIFS/SMB and NFS||Windows NAS proxy and Linux NAS proxy||CIFS/SMB and NFS|
The Discover Shares feature will automatically discover shares only if your NAS device is mapped to a NAS proxy with a proxy version 4.8.16-98358 and later.
During manual backups, Phoenix only backs up data as defined in the backup policy. The backup window defined in the backup policy does not restrict a manual backup. Instead, it continues until all the data is backed up. In the event of a network connection failure during backup, the NAS proxy attempts to connect to the Phoenix Cloud. After the connectivity is restored, backup resumes from the state in which it was interrupted. Network bandwidth does not restrict a manual backup, as it uses the maximum bandwidth available.
Note : The Automatic Retry feature does not work with manual backups.
Back up empty folders
Phoenix can back up and restore empty folders. On SMB shares, the USN journal must be enabled to back up and restore an empty folder.
Smart Scan uses heuristics to ensure that incremental backups are faster by optimizing the time it takes to scan files and folders. By default, the Smart scan option is disabled. You can enable this option while creating or editing a backup policy on the Backup Schedule tab. Here are the options that you can select while enabling Smart scan:
- Skip ACLs for unmodified files from being scanned
- Scan files and folders that are created or modified in the last x months. For example, 3 months.
Based on the options selected, Phoenix decides which files and folders need to be scanned during incremental backups.
- The Skip ACL scan for unmodified files option is applicable only for UNC share on Windows.
- If you change the Backup Content setting under the backup set, the subsequent scan is a full scan.
File types supported for backup
While creating a backup set for a NAS share, you can use content rules to configure the folders to be included in or excluded from backups. You can also define file types that must be excluded from or included in the NAS share backup.
The file types that are excluded by default are video files, audio files, All Executables, Executables, and image files. The file types that are included by default are Office files, All Office files, PDF files, and HTML files.
Phoenix also backs up and restores the Symlink and Hardlinks file system objects. Note that only the link files are backed up and not the content of the files or directories they point to.
The following table lists the file types that you can include and exclude from the backup policy.

Folders excluded from NAS share backup
By default, Phoenix excludes certain folders from the NAS share backup, since both Windows and Linux operating systems contain system-specific files, which can be excluded from backup. For example, the Recycle Bin on the Windows server contains deleted files and folders, which won't require backup.
The following table lists the default folders that Phoenix excludes from the backup.
