You can calculate the percentage of space occupied by archives from the free space on disks using the formula: A/(A+D)*100%=P%,

where:

  • A is the total volume of all created archives,
  • D is the amount of free space on a disk,
  • P is the percentage of space occupied by archives from the free space on disks.

  • When you create an archive with block or object storage type as a file, note that the disk must not be completely full. For the correct operation of the system, it is necessary to leave some space free. General recommendations for arranging free space:

    titleNote

    When you create a local archive with block storage type as a partition (logical disk), the disk can be filled completely.

    • If archive size is less than 1 TB, you need about 100 MB of free space.
    • If archive size is between 1 TB and 10 TB, you need about 1 GB of free space.
    • If archive size is larger than 10 TB, you need about 10 GB of free space.
  • For archives with object storage type, we do not recommend placing archive volumes or archives on the same physical device. If placing several archives on one physical disk is unavoidable, free space must be N times larger than the volume of all archives (N is the number of archives). We recommend splitting the archive into several volumes and placing them on different physical devices to improve the reliability and performance of storage. 

Error creating new archives even when license restriction on total capacity is observed

If the user creates archives at the same time (in other words, without applying changes) while deleting some existing archives, creation of the archives can be forbidden even if the total archive capacity does not exceed the amount of the license restriction.

Info
titleNote

This happens because when verifying the license restrictions, the size of created archives is calculated based on the total capacity at the time when changes were applied.

In such a situation, the user must first delete the unnecessary archives and apply changes, then create new archives. 

  • We recommend creating archive volumes of no more than 30 TB each.
