mc retention info

The mc retention info command configures the Write-Once Read-Many (WORM) locking settings for an object or object(s) in a bucket. You can also set the default object lock settings for a bucket, where all objects without explicit object lock settings inherit the bucket default.

To lock an object under legal hold, use mc legalhold set.

mc retention info requires that the specified bucket has object locking enabled. You can only enable object locking at bucket creation. See mc mb --with-lock for documentation on creating buckets with object locking enabled.

Example

The following command returns the default object lock configuration for the mydata bucket on the myminio AIStor deployment:

mc retention info --default myminio/mydata

Syntax

The command has the following syntax:

mc [GLOBALFLAGS] retention info            \
                 [--default]               \
                 [--recursive]             \
                 [--rewind "string"]       \
                 [--version-id "string"]*  \
                 [--versions]              \
                 ALIAS

Brackets [] indicate optional parameters.
Parameters sharing a line are mutually dependent.
Parameters separated using the pipe | operator are mutually exclusive.

Copy the example to a text editor and modify as-needed before running the command in the terminal/shell.

Parameters

ALIAS

Required

The full path to the object for which to retrieve the object lock configuration. Specify the alias of a configured S3-compatible service as the prefix to the ALIAS bucket path. For example:

mc retention info play/mybucket/object.txt

If the ALIAS specifies a bucket or bucket prefix, include --recursive to return the object lock settings for all objects in the bucket or bucket prefix.
If the ALIAS bucket has versioning enabled, mc retention info by default applies to only the latest object version.

Use --version-id or --versions to return the object lock settings for a specific version or for all versions of the object.

--default

Optional

Returns the default object lock settings for the bucket specified to ALIAS.

If specifying --default, mc retention info ignores all other flags.

--recursive

Alias: -r

Optional

Recursively returns the object lock settings for all objects in the specified ALIAS path.

Mutually exclusive with --version-id.

--rewind

Optional

Directs mc retention info to operate only on the object version(s) that existed at specified point-in-time.

To rewind to a specific date in the past, specify the date as an ISO8601-formatted timestamp. For example: --rewind "2020.03.24T10:00".
To rewind a duration in time, specify the duration as a string in #d#hh#mm#ss format. For example: --rewind "1d2hh3mm4ss".

--rewind requires that the specified ALIAS be an S3-compatible service that supports Bucket Versioning. For AIStor deployments, use mc version to enable or disable bucket versioning.

--version-id

Alias: --vid

Optional

Directs mc retention info to operate only on the specified object version.

--version-id requires that the specified ALIAS be an S3-compatible service that supports Bucket Versioning. For AIStor deployments, use mc version to enable or disable bucket versioning.

Mutually exclusive with any of the following flags:

--versions
--rewind
--recursive

--versions

Optional

Directs mc retention info to operate on all object versions that exist in the bucket.

--versions requires that the specified ALIAS be an S3-compatible service that supports Bucket Versioning. For AIStor deployments, use mc version to enable or disable bucket versioning.

Use --versions and --rewind together to retrieve the retention settings for all object versions that existed at a specific point-in-time.

Global Flags

This command supports any of the global flags.

Examples

Retrieve Object Lock Settings for an Object or Object(s)

Specific Object

mc retention info ALIAS/PATH

Replace ALIAS with the alias of a configured S3-compatible host.
Replace PATH with the path to the object.

Multiple Objects

Use mc retention info with --recursive to retrieve the retention settings for all objects in a bucket:

mc retention info --recursive ALIAS/PATH

Replace ALIAS with the alias of a configured S3-compatible host.
Replace PATH with the path to the bucket.

The bucket must have object locking enabled to use this command. You can only enable object locking when creating a bucket.

See mc mb --with-lock for more information on creating buckets with object locking enabled.

Retrieve Default Object Lock Settings for a Bucket

Use mc retention info with --default to retrieve the default object lock settings for a bucket:

mc retention info --default ALIAS/PATH

Replace ALIAS with the alias of a configured S3-compatible host.
Replace PATH with the path to the bucket.

The bucket must have object locking enabled to use this command. You can only enable object locking when creating a bucket. See mc mb --with-lock for more information on creating buckets with object locking enabled.

S3 Compatibility

The mc commandline tool is built for compatibility with the AWS S3 API and is tested with AIStor and AWS S3 for expected functionality and behavior.

AIStor provides no guarantees for other S3-compatible services, As their S3 API implementation is unknown and therefore unsupported.

While mc commands may work as documented, any such usage is at your own risk.
