You can create and configure archives on the Archive tab. To create archives, you must have appropriate permissions (see Roles). You can create an unlimited number of archives on the basis of one server.

When you select the Server object on the Archive tab, the following information is displayed:

Info
title Note
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 select the Archive object, the following information is displayed:

1. The Partitions information section displays the percentage of the filled archive volume. This parameter allows you to track the moment when the volume overwriting starts. If the volume is 100% full, it means that the new data is written over the old data (see Statuses of archive volumes).
2. The Filled archive volume field in the Archive parameters section displays the approximate volume of filling of the entire archive in percent and gigabytes.

Type of archive	Features of archive storage	Restrictions on archive volumes	Configuration features
Local	Archive can be stored on several logical disks of the server	On one logical disk for one archive, you can create only one archive volume, which occupies either a file of a set size or the entire partition (logical disk)	Archive can contain several volumes that can be in the form of a file or a partition. Archive can either have a block or object storage type
Remote	Archive can be stored in several remote storages	Archive can be stored only as a file of a specified size	Archive can either have a block or object storage type
Cloud	Archive can be stored in one cloud storage	Archive can contain several volumes of unlimited size. You can change the size of the archive without restarting ngp	You can create an archive based on the following solutios solutions (see General information about a cloud archive): Amazon S3.

1. Create an archive (see Creating archives).
2. Configure recording of camera streams to an archive (see see Configuring recording to an archive).

3. Configure data replication, if necessary (see Configuring data replication). Data from a local, remote, or cloud archive can be copied to other local, remote, or cloud archives.

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

  Info
  title Note
  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 using an archive as a single volume of large size. You must split the archive into several volumes and place them on different physical devicesplacing 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. 
• We recommend creating archive volumes of no more than 30 TB each.
