Managing the backup and recovery of the File servers in a distributed environment is usually a complex process involving multiple staff and a complex infrastructure. Phoenix facilitates you by centralizing the backup and recovery of globally distributed File servers.
Phoenix uses server-side and client-side components to interact, manage, and control backups in your File servers.
Phoenix offers you a viable, cost-effective way of storing, managing, archiving, and recovery of your data on File servers that run on Windows and Linux platforms in your environment. Phoenix supports backup and restore of the data deduplication-enabled volumes on Windows 2012 File server. Phoenix performs a non-optimized backup and restore in this case. Files on deduplication-enabled volumes are backed up as normal files and not as optimized files. Files backed up from deduplication-enabled volumes will be restored as normal files, even if restored to deduplication-enabled volumes.
Phoenix components for File server
Phoenix Cloud: Phoenix Cloud is the server component of Phoenix that authenticates and authorizes incoming backup and restore requests from Phoenix agent, installed on your File servers, and redirects it to Phoenix storage for fulfilling the requests.
- Phoenix Management Console: Phoenix Management Console is a web-based, unified console that provides complete visibility and high-level understanding of the health and status of File servers that you manage, wherever those File servers reside. You can globally view all your File servers located in your storage infrastructure, discover File servers, and configure them for backup, recovery, and archival of data. It provides Phoenix administrators ability to –
- Register and configure File servers for backup in their organization’s server infrastructure.
- Control Phoenix activities by defining backup policy, retention policy, and more.
- Monitor backup and recovery jobs, activities, and reports.
- Phoenix Agent: Phoenix agent is a client-side component, which is installed individually on each File server. You must deploy the Phoenix File server agent and register it for backing up and restoring File servers in your setup.
- Phoenix CloudCache: Phoenix CloudCache is a dedicated server that temporarily stores backup and restores data from Phoenix agent. Then, at periodic intervals, Phoenix CloudCache synchronizes this data to Phoenix Cloud relaxing the bandwidth consumption in your infrastructure.
File types supported for backup
Phoenix provides defined file types that you can include in your backup or exclude from your backup. In the Add backup policy wizard, you can configure the Exclude file types and Include file types options to exclude and include the required files types.
- File types that are by default excluded: Video files, Audio file, Executables, Image files.
- File types that are by default included: Office files, PDF files, HTML files.
You can change the default selections by adding or removing the defined file types.
The following table lists the defined file types that you can use for including and excluding file types from the backup policy.
|Defined file types||File extensions|
|Office files||.doc, .ppt, .xls, .docx, .docm, .xlsx,
.xlsm, .xts, .xltm, .pptx, .pptm, .odt, .odb, .ods, .odp, .odg, .odc, .odf, .odi, .odm, .ott, .ots, .otp, .otg, .otc, .otf, .oti, .oth, .txt, .adp, .adn, .accdb, .accdr, .accdt, .accde, .dotx, .xltx, .mdb, .mda, .mdt, .mdw, .mdf, .mde, .mam, .maq, .mar, .mat, .maf, .ppl
|Image files||.gif, .jpg, .bmp, .png, .tif, .jpeg, .raw, .pic, .pct, .pxr, .sct, .ico, .PSD|
|HTML files||.html, .htm, .mht, .mhtml, .shtml|
|Audio files||.ogg, .mp3, .wav, .flac, .mpc, .au, .aiff, .aac, .m4a, .ra, .ape, .wma|
|Video files||.avi, .mpg, .mpeg, .divx, .rmvb, .wmv, .mov, .rm, .swf, .flv, .mkv, .3gp, .mp4|
|Executables||.exe, .dll, .msi, .com, .drv, .sys, .cpl, .ocx, .msp|
Folders excluded from File server backup
By default, Phoenix excludes certain folders from File server backup. This is because, both Windows and Linux operating systems contain system-specific files, which can be excluded from backup. For example, the Recycle Bin on Windows servers contains files and folders that you previously deleted, so these files can be excluded from the backup.
The following table lists the folders that Phoenix excludes from backup. While creating a backup policy, these folders appear as excluded folders under the Exclude subfolders field.
Note: To include the folders that Phoenix excludes by default on the Backup Content tab, click the cross icon for the folder that you want to include.
|Name of operating system||Folder names|
Phoenix provides the following backup features for File servers. This section explains the various capabilities of a File server:
- Manual backup
- Backup empty folders
- Pre backup and post backup scripts
- Backup servers with mixed workload (Backup sets)
- Smart scan
- During manual backups, Phoenix only backs up data that is defined in the backup policy.
- A manual backup is not restricted by the backup window that you defined in the backup policy; it continues till all the data is backed up.
- In the event of a network connection failure during backup, Phoenix agent or backup proxy attempts to connect to Phoenix Cloud. After the connectivity is restored, backup starts from the state in which it was interrupted.
- A manual backup is not restricted by bandwidth, it uses maximum bandwidth available.
- The Automatic Retry feature does not work with manual backups.
Backup empty folders
From version 4.6.8 and later, Phoenix can backup and restore empty folders. After the upgrade, the Windows File server agent where USN journal is enabled:
- The empty folders created before the last backup and before the agent upgrade are not backed up. Contact Druva Support to backup these empty folders.
The empty folders created after the last backup but before the agent upgrade are backed up.
The Windows File server agent where UNC share is configured for backup, empty folders in the UNC share, created before and after the upgrade will be backed up and restored.
After the Linux File server agent upgrade, the empty folders created before and after the upgrade will be backed up and restored.
Pre backup and post backup scripts
Phoenix allows administrators to configure File server agents to execute custom pre-backup scripts and post-backup scripts. Pre-backup scripts are executed before backup jobs to perform specific pre-backup operation. Post-backup scripts are executed after backup jobs to perform specific post-backup operation. You can configure backup policy with the settings for pre-backup and post-backup scripts to perform customer-driven processing tasks. For more information, see Pre backup and post backup scripts for File server.
Backup servers with mixed workload (Backup sets)
Phoenix extends its backup capabilities for servers that run mixed workloads. This feature provides ability to configure multiple dataset backups of File server (Windows) and MS-SQL Database server for a single server. For more information, see Backup servers with mixed workload (Backup sets).
The Smart scan feature optimizes the scanning duration for backup. To optimize the scanning duration, Smart scan excludes scanning of Access Control Lists (ACLs) for the files that are not modified since the last backup. ACL metadata and permissions do not change daily and scanning these ACL attributes is time consuming. That is why Smart scan will exclude the scan of ACLs for the files that are not modified since the last backup, and scan it only during the last scheduled backup of the month.
By default, the Smart scan option is disabled. You can enable this option while creating or editing a backup policy. For more information, see:
Note: This feature is not applicable for Linux as ACLs are not supported on Linux.
