With Move Detection
Specifies that NetBackup also collect the information required to detect files
and directories that have been moved, renamed, or newly installed and then
include those files and directories in incremental backups for this class.
NetBackup accomplishes move detection by comparing path names with those
from the previous full or incremental backup. If a name is new or changed, the
file or directory is backed up. Without move detection, only archive bits are
considered.
The following are examples of move detection:
• A file named
C:\pub\doc
is moved to or installed in
C:\spec\doc.
Here, the archive bit is unchanged but
C:\spec\doc
is new in the
C:\spec
\ directory and is backed up.
• A directory named
C:\security\dev\
is renamed as
C:\security\devices\
. Here, the archive bit is unchanged but
C:\security\devices\
is a new directory and is backed up.
NetBackup starts collecting information required for move detection beginning
with the next full or incremental backup for the class. This first backup after
setting the attribute, always backs up all files, even if it is an incremental.
Move detection takes space on the client and the backup can fail if there is not
enough disk space available.
Example of a True-Image Restore
The following table shows the contents of the
C:\home\abc\doc
directory
during a series of backups between 12/01/1995 and 12/04/1995.
