mc du

The mc du command summarizes the disk usage of buckets and folders. You can also use mc du against the local filesystem to produce similar results as the du command.

mc du myaistor/mybucket

825KiB 3 objects        mybucket

mc [GLOBALFLAGS] du                    \
                 [--depth]             \
                 [--recursive]         \
                 [--rewind]            \
                 [--versions]          \
                 ALIAS [ALIAS ...]

Required

The alias of an AIStor deployment and the full path to the folder. For example:

mc du myaistor/mybucket

You can specify multiple buckets and folders on the same or different AIStor deployment. For example:

mc du myaistor/mybucket myaistor/myotherbucket/myfolder

For a folder on a local filesystem, specify the full path to that folder. For example:

mc du ~/data/images

The time required for mc du to complete depends on the size of the target buckets and folders. A large bucket may take some time to generate a disk usage summary.

Optional

Print the total for all folders N or fewer levels below the path specified in the command. Default is 0, for the specified path only.

Alias: -r

Optional

Recursively print the total for each bucket or child folder.

Optional

Directs mc du 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#ssformat.

  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.

Use --rewind and --versions together to show the disk usage for those object versions which existed at a specific point in time.

Optional

Directs mc du 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 show the disk usage for those object versions which existed at a specific point in time.

This command supports any of the global flags.

Use mc du to print a summary of the disk usage for a bucket or folder:

mc du ALIAS/PATH

• Replace ALIAS with the alias of the S3-compatible host.
• Replace PATH with the path to the bucket or folder on the S3-compatible host.

Use mc du --rewind to print a summary of disk usage at a specific point-in-time in the past:

mc du --rewind DURATION ALIAS/PATH

• Replace DURATION with the desired point-in-time in the past.

  For example, specify 30d to show the disk usage 30 days prior to the current date.

• Replace ALIAS with the alias of the S3-compatible host.

• Replace PATH with the path to the bucket or folder on the S3-compatible host.

Use mc du --recursive to print a summary for each folder recursively:

mc du --recursive ALIAS/PATH

• Replace ALIAS with the alias of the S3-compatible host.
• Replace PATH with the path to the bucket or folder on the S3-compatible host.

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.

MinIO 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.
