About this task

This topic describes how to create archives manually. You can also create them automatically. When the current archive is full, a new archive is used (in a sequential order).

You can create multiple archives at the same time.

Procedure

  1. Access Historian Administrator.
  2. Select DataStores.
  3. Select Add New Archive(s).
    The Add New Archive(s) window appears.
  4. Enter values as described in the following table.
    Field Description
    Archive Name Enter a unique name for the archives. The value must be the same as the file name. When multiple archives are created, a number is appended to the name to make each name unique (and to maintain a sequence).
    Data Store Select the data store in which you want to create the archives.
    File Location Enter the path to the folder in which you want to store the archives, or specify a UNC path.
    EachArchive Size (MB) Enter the size, in MB, that you want to allocate to the archives.
    Number of Archives Enter the number of archives you want to create.
    Important: Ensure that the number of archive files does not exceed 1024. Otherwise, the archiver will crash. This is because 1024 is the default number of file descriptors a process can open on Linux. We recommend that you create archive files daily or by size so that you can monitor the number of archive files created.
    Allocate Space Specify the percentage of the disk space that you want to allocate for archives. As you increase the space, the number of archives increases accordingly.
    Note: The Allocate Space field does not display a remote machine's hard disk space; if you are creating multiple archives on a remote machine, you must ignore the ”r;percentage of available disk space will be used” message displayed by the Allocate Space slider.
  5. Select OK.
    The archives are created.
