Access Control List. A list that contains the users' or groups' access rights to each share.
A file system excluding its Snapshot copies.
A manageable unit of RAID-protected storage, consisting of one or two plexes, that can contain one traditional volume or multiple FlexVol volumes.
The number of tape blocks that are transferred in each write operation.
Common Internet File System. A protocol for networking PCs.
A terminal that is attached to a storage system's serial port and is used to monitor and manage storage system operation.
Domain Naming Service. An Internet service for finding IP addresses.
A path that specifies one volume, qtree, or subtree to back up.
Data on a tape that signals a boundary of a tape file.
HyperText Transfer Protocol. An Internet Web transfer protocol.
A series of incremental backups of the same path.
A data structure containing information about files on a storage system and in a UNIX file system.
A program-based functionality associated with a tape drive that is directly attached to a storage system that is performing a tape operation.
Message Digest 5. A checksum algorithm described in RFC (Request For Comments) 1321, a proposal for an Internet standard.
A volume that contains a read-only copy of data in the active file system of another volume, usually on another storage system.
Network Data Management Protocol. A protocol that allows Data ONTAP storage systems to communicate with backup applications, and provides capabilities for controlling the robotics of multiple tape backup devices.
Network File System. A protocol for networking UNIX-based computers.
Network Information Service, formerly called Yellow Pages. An administrative database for networks.
Software that warns you of compromised database validity and automatically renames the database so that it does not restart automatically.
Nonvolatile RAM in the storage system, used for logging incoming write data and NFS requests. Improves system performance and prevents loss of data in case of a storage system or power failure.
A system, such as a server running Solaris, HP-UX, Windows NT, or Windows 2000, whose data can be backed up to a SnapVault secondary storage system.
A software module that can be installed on a system and enables that system to back up its data to a SnapVault secondary storage system.
A physical copy of a file system. An unmirrored volume has one plex; a mirrored volume has two identical plexes.
A system whose data is to be backed up by SnapVault.
A limit placed on a file system that restricts disk space usage by files with a given User ID (UID) or group ID (GID).
A special subdirectory of the root of a volume that acts as a virtual subvolume with special attributes.
Redundant Array of Independent Disks. A technique that protects against disk failure by computing parity information based on the contents of all the disks in the array. Storage systems running Data ONTAP software use RAID Level 4, which stores all parity information on a single disk.
A program that enables a user on one system to execute a program on another system. Remote Shell connections are usually not interactive.
A program-based functionality associated with a tape drive that is not directly attached to a storage system that is performing a tape operation.
The volume that contains information that controls the entire storage system, usually in the /etc/rc file.
A storage system to which data is backed up by SnapVault.
A directory or directory structure on the storage system that has been made available to network users and can be mapped to a drive letter on a CIFS client.
Software that performs automated file system replication of a volume onto the same or a separate disk or storage system.
Software that restores an entire volume to the state recorded in a previously taken Snapshot copy.
An online, read-only copy of the entire file system that protects against accidental deletions or modifications of files without duplicating file contents. Snapshot copies enable users to restore files and enable administrators to back up the system to tape while it is in use.
The portion of a volume's disk space that is reserved for Snapshot copies.
The storage system from which you are replicating data.
A directory in a volume or qtree.
1,024 bytes of data.
A specific functionality of a physical tape drive that you create by specifying information in the tape device name when you install a tape drive or tape stacker.
Data on a tape delimited by file marks.
Hardware that can access tape cartridges randomly.
Hardware that can load and unload tape cartridges.
Hardware that can access tape cartridges from a stack.
A file system.
A way of copying both data in the active file system and data in Snapshot copies from one volume to another.
