NetVault 13.3.2 - Administration Guide

Backup immutability

If you use QoreStor for backup storage, you can select to make RDA backups immutable. RDA immutability provides protection from overwrites and deletes on backup files. This technology is present by default for RDS containers, but not all backups are protected by default. When NetVault sends data using the RDA protocol to QoreStor, you can define whether the backup data should be immutable. After you set immutability on a backup set, you cannot modify or delete the backup data from the RDA container until the predetermined length of time expires.

NOTE: The backup immutability feature is available beginning with NetVault 13.0.3 and QoreStor 7.1. It is not compatible with previous versions of NetVault. For more information, see the NetVault Supported Storage Targets Guide and the QoreStor Interoperability Guide. Backup immutability is not accessible through the command line interface or REST API.

About NetVault Sets

NetVault Sets are used to create backup and restore jobs.

You can use sets to store data selections, backup and restore options, scheduling options, device and media options, and other advanced backup and restore options. Sets eliminate the need to manually select the data items or configure backup and restore options for each job, and allow you to quickly and easily apply the same data selections and options to multiple jobs.

For example, you can save the data selections in a Backup Selection Set, and use this set to create Full, Incremental, and Differential Backup jobs to ensure that the same data set is used for all jobs. Similarly, you can change the day, date, or time in a Schedule Set to automatically change the job schedule for multiple jobs, or specify a new device for backups by changing the Target Set.

The following table describes the set types that are available in NetVault.

Backup and recovery strategy

The primary objective of backing up data is to recover from the damages caused by a data loss event and resume normal operations quickly. This objective requires a good backup strategy, which maximizes data availability and minimizes data loss and downtime, while balancing your business requirements with costs, resources, and other factors.

To create a good backup plan, consider the possible failure modes, like hardware failure, data corruption, human error, or loss of a data center, and select the suitable backup methods and features to recover from these scenarios.

Typically, your backup plan should define what backup methods are used, when and at what intervals the backups are performed, how the backups are stored, how long the backups are retained, and how the backup media are re-used.

NetVault offers the following two options for backing up data:

A typical backup job protects your servers according to your set schedule by taking full, incremental, or differential backups every specified number of days. For more information, see Creating a backup job.

A continuous backup job supports continuous data protection of data by taking a incremental backup of your data every specified amount of time. Synthetic full backups include all of the changes that have been made since the previous backup. . CDP backup job can be scheduled on the basis of date and time. The option Run at captures the system time and Starting from captures system date to start the continuous backup job. You can also schedule a CDP backup run for another date and time with these options.When combined with an initial full backup, they form a complete and current image of your data.

NOTE: Continuous backup jobs are available for Plug-in for VMware 13.1 or later and Plug-in for Microsoft 365 13.1or later, and with QoreStor 7.1.2 or later. For more information, see the NetVault Plug-in for VMware User’s Guide or the NetVault Plug-in for Microsoft 365 User's Guide. NOTE: Continuous data protection (CDP) job creation is not available through guided configuration. .

Creating a backup job

You can use the backup job wizard to create and submit backup jobs. The wizard can be accessed from the Guided Configuration or Create Backup Job link in the Navigation pane.

NOTE: A job that uses the Schedule Type “Triggered” is only scheduled when you run the script.
