Definition:

Prefix of a snapshot that is automatically created, which is manually entered.

Constraints:

N/A

Value range:

Enter up to 32 characters and start with a lowercase letter. Lowercase letters, digits, hyphens (-), and underscores (_) are allowed.

Default value:

N/A

keepday

Set the number of snapshots to be retained. Expired snapshots will be automatically deleted on the half hour. The deletion policy applies only to automated snapshots that are executed at the same frequency as the current automatic snapshot creation policy.

Constraints:

N/A

Value range:

1–90

Default value:

N/A

bucket

N/A

Value range:

Only a-z, A-Z, 0-9, hyphens (-) and underscores (_) are allowed.

Default value:

N/A

NOTE:
If none of the bucket, basePath, and agency parameters are specified, the system will automatically create an OBS bucket and an IAM agency. If the creation fails, you need to manually configure correct parameters.

frequency

No

String

Definition:

Frequency of automatically creating snapshots.

Constraints:

N/A

Value range:

N/A

Default value:

DAY

When the value is HOUR, the task is executed every hour. When the value is DAY, the scheduled task is executed every day. When the parameter is set to SUN, MON, TUE, WED, THU, FRI or SAT, the scheduled task is executed at the specified day of every week. The number of retained snapshots depends on the execution frequency and indexes set in the automatic snapshot creation policy. If the execution interval is short or the index data volume is large, the number of retained automatic snapshots may not reach the preset value. Set this value based on actual conditions.

maxSnapshotBytesPerSeconds

No

String

Definition:

This parameter sets the maximum backup speed per node (bytes per second). When it is exceeded, flow control is triggered to prevent excessive resource usage and ensure system stability. The actual backup speed may not reach the configured value, as it depends on many factors, such as OBS performance and disk I/O.

Constraints:

N/A

Value range:

The following values and formats are allowed:

  • Number + Unit

The number ranges from 0 to 9999.

The unit can be k, kb, m, mb, g, gb, t, tb, p, pb, or b (case-insensitive).

0mb means there is no speed limit. An overly high backup speed may lead to excessive resource usage, which may impact system stability. Therefore, set this parameter carefully.

  • 0

There is no speed limit. An overly high backup speed may lead to excessive resource usage, which may impact system stability. Therefore, set this parameter carefully.

  • -1

There is no speed limit. An overly high backup speed may lead to excessive resource usage, which may impact system stability. Therefore, set this parameter carefully.

Default value:

The default value is 40 MB. If this parameter is left blank, the default value is used.

maxRestoreBytesPerSeconds

No

String

Definition:

This parameter sets the maximum recovery speed per node (bytes per second). When it is exceeded, flow control is triggered to prevent excessive resource usage and ensure system stability. The actual recovery speed may not reach the configured value, as it depends on many factors, such as OBS performance and disk I/O.

Constraints:

For OpenSearch clusters and Elasticsearch clusters later than 7.6.2, the recovery speed is also limited by the indices.recovery.max_bytes_per_sec parameter. If Maximum recovery speed (per second) is lower than indices.recovery.max_bytes_per_sec, flow control is triggered when the former is reached. If Maximum recovery speed (per second) is higher than indices.recovery.max_bytes_per_sec, flow control is triggered when the latter is reached.

Value range:

The following values and formats are allowed:

  • Number + Unit

The number ranges from 0 to 9999.

The unit can be k, kb, m, mb, g, gb, t, tb, p, pb, or b (case-insensitive).

0mb means there is no speed limit. (However, for OpenSearch clusters and Elasticsearch clusters later than 7.6.2, the recovery speed is also limited by the indices.recovery.max_bytes_per_sec parameter.) An overly high recovery speed may lead to excessive resource usage, which may impact system stability. Therefore, set this parameter carefully.

  • 0

There is no speed limit. (However, for OpenSearch clusters and Elasticsearch clusters later than 7.6.2, the recovery speed is also limited by the indices.recovery.max_bytes_per_sec parameter.) An overly high recovery speed may lead to excessive resource usage, which may impact system stability. Therefore, set this parameter carefully.

  • -1

There is no speed limit. (However, for OpenSearch clusters and Elasticsearch clusters later than 7.6.2, the recovery speed is also limited by the indices.recovery.max_bytes_per_sec parameter.) An overly high recovery speed may lead to excessive resource usage, which may impact system stability. Therefore, set this parameter carefully.

Default value:

For Elasticsearch clusters of 7.6.2 or earlier, the default setting is 40mb.

For OpenSearch clusters and Elasticsearch clusters later than 7.6.2, the default setting is no limit, but the recovery speed is still limited by the indices.recovery.max_bytes_per_sec parameter.

If this parameter is left blank, the default setting is used.
