Exclusion list considerations

•
The NetVault Backup Plug‑in for FileSystem supports the following special characters in an exclusion list.
 
Character
Description

/

Used to terminate Linux and UNIX file paths.

\

Used to terminate Windows file paths.

?

Used to match any one character.

!n

Used to insert new line.

!r

Used to insert carriage return.

!t

Used to insert tab.

!f

Used to insert form feed.

!b

•
File and directory names are case-sensitive on Linux and case-insensitive on Windows.
•
Spaces are not ignored.
•
To insert comments, use # at the starting of each line.
•
An exclusion list should not include any System State components on Windows, especially Windows File Protection and SYSVOL files on a Domain Controller.
•
An exclusion list cannot contain files or paths with non-ASCII characters. Such entries can cause a backup to fail.

About backup methods

The NetVault Backup Plug‑in for FileSystem supports the following backup methods:

•
Standard Backup method: This method lets you perform native file system backups. The Standard Backup method is supported on all operating systems.
On Linux- and UNIX-based systems, only the Standard Backup method is available for backing up the file system data.
•
Volume Shadow Copy Service (VSS) Backup method: This method lets you perform snapshot-based backups. The VSS Backup method is only supported on Windows-based systems.
When this method is selected, the plug-in uses a VSS provider to create consistent point-in-time copies of data known as shadow copies. Shadow copies have two primary advantages:
•
They allow creation of consistent backups of a volume, ensuring that the contents do not change while the backup is being performed.
•
They avoid problems of file locking. By creating a read-only copy of the volume, backup programs are able to access every file while minimizing interruption to other applications writing to those same files.

About backup types

The NetVault Backup Plug‑in for FileSystem supports the following backup types:

•
Full Backup: A Full Backup provides a backup of all selected files and folders. Full Backups take longer to complete and consume more backup media. However, restores are faster since the plug-in is only required to restore a single saveset. Full Backups serve as the base backups for subsequent Incremental and Differential Backups.
•
Incremental Backup: An Incremental Backup provides a backup of files that are new or have changed since the last Full or Incremental Backup. Incremental Backups consume minimum storage space and are quicker to perform. However, data recovery can take more time depending on the number of savesets that the plug-in is required to restore.
•
Differential Backup: A Differential Backup provides a backup of files that are new or have changed since the last Full Backup. Differential Backups speed up recovery since the plug-in is only required to restore two savesets. However, these backups consume more storage space and take more time to complete than the Incremental Backups. Differential Backups duplicate the data backed up by previous backups of the same type.
