Overview - UNIX/Linux File Systems

Introduction

SnapProtect software provides a simplified end-to-end protection of file system data residing on all the UNIX computers in your enterprise.  In addition to complete protection of file system data for disaster recovery, it also provides a robust and comprehensive backup and recovery solution with significant speed performance and efficient use of disk and tape drives. It also assists you in full system rebuilds and eliminates recovery failures.

You can back up and access the data that is exported as NFS shares on the file server. For more information, see Data Protection for NFS Shares, CIFS Shares, and UNC Paths.

Key Features

The UNIX File System iDataAgent offers the following key features:

Simplified Data Management

The UNIX File System iDataAgent enables easy management of all the UNIX systems in your environment, by providing a singular approach to manage the data using the same unified console and infrastructure.

Point-in-Time Recovery

In the event of a serious system failure, such as the breakdown of hardware, software, or operating systems, the UNIX File System iDataAgent provides point-in-time recovery of files at any given time.

Backup and Recovery Failovers

In the event that the MediaAgent used for the backup or recovery operation fails, the backup is automatically resumed on an alternate MediaAgents. In such cases, the backup or restore job does not restart from the beginning, but resumes from the point of failure. This is useful for backups and restores of large amount of file system data.

In the event that a network goes down, the backup and recovery jobs are resumed on alternate data paths. Similarly, in the event of a device failure, the jobs are automatically switched to alternate disk and tape drives.

Efficient Job Management and Reporting

You can view and verify the status of backup and recovery operations from the Job Controller and the Event Viewer within the CommCell Console. You can also track the status of the jobs using Reports, which can be saved and distributed. Generate reports for different aspects of data management. Customize the reports to display only the required data and save them to a specific location in different formats. For example, you can create a backup job summary report to view the completed backup jobs.

You can schedule, generate and send the Reports via email without user intervention. 

Block-Level Deduplication

Deduplication provides a smarter way to store 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 (such as, file, database) contains blocks of data that are identical to each other, then block-level deduplication does not store the redundant data, which reduces the size of the object in storage. This reduces the size of the backup data copies on both the disk and tapes.

Resource Allocation

Control resource allocation, re-allocation, de-allocation, and tracking of processes at group level using Resource Control Groups (RCG) for SnapProtect. For more information, see Resource Control Groups.

Add-on Components

1-Touch

1-Touch recovery helps to recover a crashed system in the least amount of time, by automatically rebuilding the operating system. You can also recover systems with defective components such as inaccessible volumes or crashed disks. You don't need to reinstall the individual software packages or operating systems manually.

OnePass

OnePass is an integrated File System agent that backs up and archives data which meets the archiving rules that can be established for your environment. OnePass also reclaims backup storage space when files and stubs are deleted on the primary storage.

Content Indexing and Search

Content Indexing and Search enables users to content index their data and later search the data from a user-friendly web interface. The users can also perform restore operations or other advanced actions on the searched data.

Terminology

The UNIX File System documentation uses the following terminology:

Client

The computer in which the iDataAgent is installed and contains the data to be secured.

Backup Set

A group of subclients which includes all of the data backed up by the  iDataAgent.

Subclient

The UNIX file system data to be backed up.
