Tech Note #: 9105
Date: March 22, 1991
Subject: Taglist File Format
Keywords: FILE FORMAT TAG TAGLIST TAGTYPE
A taglist file is created after files have been tagged, and the
Select/Write Tags option is chosen in the Network Archivist
Comprehensive Menu. The Select/Read Tags option is used to read an
existing taglist file.
The two most common uses of taglists are for managing the migration
process and creating a batch file for selective tape operations such as
Checkpointing database files every x-hours.
Taglist File Format
The taglist is an ASCII, comma and quote delimited file with one tag
record, containing nine fields, per line.
Taglist Record Fields
Directory Name of the directory the file is in. Used to
locate the tagged file on disk. This directory
path is applied to the current volume.
Filename Name of the tagged file. Used to locate the
tagged file on disk.
Owner Name of the NetWare identified owner of the file.
Size Size of the file in bytes. Used to match the
tagged version of the file with the appropriate
file in the Archive History.
Tagtype Used to identify which tagging method was used to
select the file.
"=" An equal sign tagtype indicates a tag of a
specific file by time stamp and file size.
This tagtype occurs when tagging a specific
version of a file from the History window
or when tagging a "not-the-most-recent"
version of a file when a Date Filter is
active. During a restore, the Network
Archivist will only restore the file if an
exact match, by time stamp and file size,
is found.
">" A greater than tagtype indicates that a
non-specific version of the selected file
was tagged.
During a restore using a taglist this
"generic" tag indicates the most recent
version of the file will be restored.
"~" A tilde tagtype indicates that the tagged
file is dormant.
This tagtype is created when a file is
tagged using the Select Eligible command to
scan for dormant files eligible for
migration.
When reading a taglist, if the tagtype is a
tilde, the Network Archivist will recheck
the file's eligibility for migration. If
the Last Accessed Date still indicates that
the file meets the criteria for migration
the file will be retagged. If the file has
been 'touched' since the taglist was
created, or if the file no longer exists on
disk, it will not be retagged.
If you do not want the Network Archivist to
recheck for migration eligibility, edit the
taglist to replace the "~" with a ">"
symbol.
ModDate Date and time the file was last modified. Used
to match the tagged version of the file with the
appropriate file in the Archive History.
AccDate Date and time the file was last accessed. Access
includes anytime the file was read, written, or
executed.
ArcDate Date the file was last archived. The Network
Archivist sets the archive date when it
checkpoints or saves a file.
Fullname Full name of the NetWare identified file owner.
