Archive properties

Right-click an archive and choose Properties to see a list of the following information for an archive:

• Archive File name, which includes the full path and drive letter relative to the server machine.

• The Data Archive network name or IP address.

• The name of the Collective, if applicable, that the Data Archive belongs to.

• The current Status of the archive, either Primary, Has Data, or Empty.

  Note: Each server has one primary archive where data is currently collected. Only historical archives can be primary archives; future archives used for forecast data cannot be primary archives.

• The Size of the archive in megabytes.

• The Start Time of the archive, when the first data was stored in the file.

  Note: Current Time indicates an empty archive.

• The End time of the archive, when the last data was stored prior to an archive shift.

  If the end time is Current Time and start time is not, then the archive is the primary archive. If start and end times are both Current Time, then the archive is empty.

• The Lifetime of the archive, or the cumulative duration over which data was stored in the file (d hh:mm:ss:0)

• The Last Modified Time, which indicates the last time the archive was modified.

• The most recent Backup Time of the archive.

• The State of the archive file, either Created, Initialized, Dismounted, or Mounted.

• The archive file Type, either Fixed or Dynamic in size.

• The Write Flag, which indicates if the file is Writable or Read-Only.

• The Shift Flag, which indicates if the file is Shiftable or Not Shiftable.

• The Add Rate/Hour, recording the average number of values stored per hour over the lifetime of the archive file.

• The % Full, indicating the amount of space already used up in the archive.

  Note: Dynamic archives are always 100% full.

• The number of Annotations in the file, divided by the total number of stored values.

• The Annotation File Size, recording the size of the accompanying file used to store annotations, in kilobytes.

• For primary archives, the Shift Prediction indicates the estimated time the archive will fill and the server will shift to a new primary archive.

• Primary Offset are the start and end record numbers for primary records. The end record number is always 1/2 of the Record Count.

• Overflow Offset are the start and end record numbers for overflow records.

• Record Size is the size in bytes of one record. This is always 1024.

• Version is an identifier of the archive's internal architecture. This label allows Data Archive to mount and upgrade archives from older versions.

• An Archive Number that indicates the archive file's order of use by Data Archive.
