Arcserve UDP Terms and Definitions

Agent-Based Backup

An Agent-Based backup is a method to back up data using an agent component. The agent is installed on the source node.

Compression

Related Topics:

Data Deduplication

Compression is used for backups. Compression is often selected to decrease disk space usage, but also has an inverse impact on your backup speed due to the increased CPU usage.

The available options are:

No Compression

This option has the lowest CPU usage (fastest speed), but also has the highest disk space usage for your backup image.

Standard Compression

Some compression is performed. This option provides a good balance between CPU usage and disk space usage. This is the default setting.

Maximum Compression

Maximum compression is performed. This option provides the highest CPU usage (lowest speed), but also has the lowest disk space usage for your backup image.

Notes:

configuration

A tab on the Arcserve UDP Console to define configuration parameters such as email alerts, database settings, and installation preferences.

dashboard

A tab on the Arcserve UDP Console that lets you view the last Backup status and storage status. You can view the the latest Actual, Raw and Restorable Data storage.

Data Store

A data store is a physical storage area on a disk. You can create a data store on any Windows system where the recovery point server is installed. Data stores can be local or on a remote share that the Windows system can access.

Destination

Destination is a computer or server where you store backup data. A destination can be a local folder on the protected node, a remote shared folder, or a Recovery Point Server (RPS).

Discovered Nodes

Discovered nodes are physical or virtual systems that are added to the Arcserve UDP Console by discovering them from active directory or vCenter/ESX server, importing from a file, or manually adding them using its IP address.

Encryption

The Arcserve UDP solution provides encryption feature for data.

When the backup destination is a recovery point server, the available encryptions are No Encryption and Encrypt data with AES-256. You can set this to create a data store. When the backup destination is the local or remote share, the available encrypt format options are No Encryption, AES-128, AES-192, and AES-256. You can set the option while creating a plan to backup to local or share folder, or set this from backup setting for standalone Arcserve UDP Agent.

Key Features of Encryption:

  1. AES256 encryption method applies to:
  2. For Backup job: If encryption is enabled, data is encrypted before sending out of the server.
  3. For Replication job: If replication destination has encryption enabled, data is encrypted before sending out of the server.

Encryption settings

  1. Select the type of encryption algorithm that you want to use for backups.

    Data encryption is the translation of data into a form that is unintelligible without a deciphering mechanism. The Arcserve UDP solution uses secure, AES (Advanced Encryption Standard) encryption algorithms to achieve maximum security and privacy of your specified data.

  2. When an encryption algorithm is selected, provide (and confirm) an encryption password.

    For example, if you change the encryption password and submit a customized incremental or verify backup manually, it automatically converts to a full backup.

    Note: This option is available only for the local or remote share destinations. You cannot disable the encryption setting if the Arcserve UDP agent is backed up to data store.

  3. The Arcserve UDP solution has encryption password and session password.

    A password is not required when you are attempting to restore to the computer from which the backup was performed. However, when you attempt to restore to a different computer, a password is required.

Host-Based Agentless Backup

A Host-Based Agentless backup is a method to back up data without using an agent component on the source machine.

HOTADD Transport Mode

The HOTADD transport mode is a data transport method that lets you back up virtual machines configured with SCSI disks. For more information, see the Virtual Disk API Programming Guide on the VMware website.

Job

A job is an Arcserve UDP action to back up, restore, create virtual standby, or replicate nodes.

jobs

A tab on the Arcserve UDP Console that lets you monitor the status of all jobs such as backup, replication, and restore. The details include jobs, task types, node IDs, recovery points, and plan names.

NBD Transport Mode

Network Block Device (NBD) transport mode, also referred to as LAN transport mode, uses the Network File Copy (NFC) protocol to communicate. Various VDDK and VCB operations use one connection for each virtual disk that it accesses on each ESX/ESXi Server host when using NBD.

NBDSSL Transport Mode

Network Block Device Secure Sockets Layer (NBDSSL) transport mode uses the Network File Copy (NFC) protocol to communicate. NBDSSL transfers encrypted data using TCP/IP communication networks.

Nodes

A node is a physical or virtual system that Arcserve UDP protects. Arcserve UDP can protect physical nodes and virtual machines in a vCenter/ESX or Microsoft Hyper-V server.

Plan

A plan is a group of tasks to manage backup, replication, and creation of virtual standby machines. A plan consists of a single or multiple tasks. Tasks are a set of activities to define the source, destination, schedule, and advanced parameters.

Protected Nodes

Protected nodes are the nodes that have scheduled backup plans to back up data on regular intervals.

Recent Event

Recent Events are the jobs that are still running or jobs that were recently completed.

Recovery Point

A recovery point is a point in time backup snapshot of a node. A recovery point is created when you back up a node. Recovery points are stored on the backup destination.

Recovery Point Server

A recovery point server is a destination node where you install the server. You can create data stores in a recovery point server.

Replicate

Replicate is a task that duplicates the recovery points from one server to another server.

Resources

resources is a tab on the Arcserve UDP Console. From the resources tab, you can manage source nodes, destinations, and plans.

SAN Transport Mode

The SAN (Storage Area Network) transport mode lets you transfer backup data from proxy systems connected to the SAN to storage devices.

Systems

Systems are all type of nodes, devices, and virtual machines that can be managed by Arcserve UDP. This includes physical, virtual, Linux, and standby virtual machines.

Tasks

A task is a set of activities to define various parameters to back up, replicate, and create virtual standby machines. These parameters include source, destination, schedule, and some advanced parameters. Each task is associated with a plan. You can have more than one task in a plan.

Unprotected Nodes

Unprotected nodes are the nodes that are added to Arcserve UDP but a plan is not assigned. When a plan is not assigned, you cannot back up data and the node remains unprotected.
