Backup (Windows): Additional considerations

This section discusses additional information to consider when backing up data.

Open files
Some files on your system might be in use when you try to back them up. These are called open files because they are locked by an application for its exclusive use.
Ambiguous file space names in file specifications
If you have two or more file spaces such that one file space name is the same as the beginning of another file space name, then an ambiguity exists when you try to restore, retrieve, query, or do another operation that requires the file space name as part of the file specification.
Management classes
IBM Storage Protect uses management classes to determine how to manage your backups on the server.
Deleted file systems
When a file system or drive has been deleted, or it is no longer backed up by the client, the existing backup versions for each file are managed according to the following policy attributes: Number of days to keep inactive backup versions, and number of days to keep the last backup version (if there is no active version).
Removable media and fixed drives
The backup-archive client backs up your removable media (such as tapes, cartridges or diskettes) and fixed drives based on the drive label, not the drive letter.
NTFS and ReFS file spaces
When you back up files on NTFS or ReFS partitions, the client also backs up file security information and file descriptors.
Universal Naming Convention names
A Universal Naming Convention (UNC) name is a network resource name for a share point on a workstation.
Microsoft Dfs file protection methods
There are some methods that you can use to protect the data in your Microsoft Dfs environment.
