Using Backup Options
Chapter 5244
is made. In the second traverse, only one hard link is backed up with the
file contents, while all the others are backed up as hard links. The first
traverse also allows Data Protector to estimate the size of the backup.
If set, Data Protector backs up the entire file contents for each hard link.
Data Protector traverses the filesystem tree only once, thus significantly
speeding up the backup process.
Use this option when there are no hard links in your directory. When
this option is set, Data Protector cannot estimate the size of the backup
or display the percentage of the backup finished.
The default value is OFF.
Catalog Protection
The default Catalog Protection value is Same as data protection. It
can be changed by specifying the None, Until, Days, and Weeks values.
Refer to “Catalog Protection: How Long Info Is Kept in the Database” on
page 230 for more information.
Do Not Preserve Access Time Attributes
When this option is not set, the access time attributes remain as they
were before the backup. (They are reset to their original values after
each file is backed up.) When this option is set, the access time values are
set to the moment of backup.
See also “Backing Up UNIX Systems” on page 161.
The default value is OFF.
Do Not Use Archive Attribute (Windows-Specific Option)
Data Protector clears the archive attribute after each backup (after the
file has been read). If you have other applications that make specific use
of this attribute, you should use this option.
The default value is OFF.
Detect NTFS Hardlinks (Windows-Specific Option)
This option is similar to Backup hardlinks as files except that it is
only valid for NTFS and the default value is OFF, meaning that hardlinks
are backed up as ordinary files. The default value is OFF because the
NTFS hardlinks are not often used and setting this option decreases
backup performance.
