Getting Started - NAS File System iDataAgent - Overview
The NAS iDataAgent provides a simplified end-to-end backup and recovery solution for the data residing on a NAS File Server. In addition to complete protection of file system data for disaster recovery, the NAS iDataAgent also provides more granular backup and recovery options that operate seamlessly with your data protection.
The NAS iDataAgent offers the following key features:
The NAS iDataAgent provides the flexibility to backup and restore the data residing on various file servers. You can perform a full, incremental, or differential backup of the entire data at any point of time. The backup data can be restored to different environments such as file servers or client computers.
Backup and restore options include the following:
- NDMP 2-way: backup and restore using tape drives on the file server client.
- NDMP 3-way: backup and restore using tape drives on other file server clients.
- NDMP 3-way: backup and restore to media attached to a MediaAgent. This method is also sometimes referred to as NDMP Remote.
In the event of a serious system failure, such as the breakdown of hardware, software, or operating systems, the NAS iDataAgent provides Point-in-Time recovery of files at any given time.
You can restore NAS data from a file server to a Windows or Unix client computer. A file system restore is a cross-platform restore, where the data is restored to a computer with a different operating system e.g., data from a NetApp file server running ONTAP can be restored to a Windows computer.
You can view and verify the status of the backup and recovery operations from the Job Controller and Event Viewer windows within the CommCell Console. You can also track the status of the jobs using reports, which can be saved and easily distributed. Reports can be generated for different aspects of data management. You also have the flexibility to customize the reports to display only the required data and save them to any specified location in different formats. For example, you can create a backup job summary report to view at-a-glance the completed backup jobs.
In addition, you can also schedule these reports to be generated and send them on email without user intervention.
Deduplication provides a smarter way of storing data by identifying and eliminating the duplicate items in a data protection operation.
Deduplication at the data block level compares blocks of data against each other. If an object (file, database, etc.) contains blocks of data that are identical to each other, then block level deduplication eliminates storing the redundant data and reduces the size of the object in storage. This way dramatically reduces the backup data copies on both the disk and tapes.
The NAS documentation uses the following terminology:
|The computer in which the iDataAgent is installed and contains the data to be secured.|
|A group of subclients which includes all of the data backed up by the iDataAgent.|
|The NAS file system data within the backupset used for backup and restore operations.|
|A device used for backup or archival purposes.|
