      DESCRIPTION

      Removes a backup repository from the backup archive. All contents of the specified repository will be deleted from disk.

      OPTIONS

      Below are a list of parameters for the remove command.

      -a,--archive <archive_dir>

      The location of the archive directory. If the archive is stored in S3 prefix the archive path with s3://${BUCKET_NAME}/.

      -r,--repo <repo_name>

      The name of the backup repository to remove.

      Optional

      --start <start>

      The first backup to remove. See START AND END for information on what values are accepted.

      --end <end>

      The final backup to remove. See START AND END for information on what values are accepted.

      --backups <backup_range>

      This flag will accept either a single backup directory (e.g. --backups 2019-08-23T09_36_56.957232625Z) a comma separated range in the same formats as --start and --end. See START AND END section for more information on the accepted formats.

      Cloud integration

      Native cloud integration is an Enterprise Edition feature which was introduced in Couchbase Server 6.6.0.

      Multiple cloud providers are supported, see the list below for more information.

      1. Supported

        • AWS S3 (s3://)

        • GCP Google Storage (gs://)

        • Azure Blob Storage in 7.1.2+ (az://)

      Required

      --obj-staging-dir <staging_dir>

      When performing an operation on an archive which is located in the cloud such as AWS, the staging directory is used to store local meta data files. This directory can be temporary (it’s not treated as a persistent store) and is only used during the backup. NOTE: Do not use /tmp as the obj-staging-dir. See Disk requirements in cbbackupmgr-cloud for more information.

      Optional

      --obj-access-key-id <access_key_id>

      The access key id which has access to your chosen object store. This option can be omitted when using the shared config functionality provided by your chosen object store. Can alternatively be provided using the CB_OBJSTORE_ACCESS_KEY_ID environment variable.

      When using AWS, this option expects an access key id. See https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys for more information.

      When using Azure, this option expects an account name. See https://docs.microsoft.com/en-us/azure/storage/common/storage-account-overview#storage-account-endpoints for more information.

      When using GCP, this option expects a client id. See https://cloud.google.com/storage/docs/authentication for more information.

      --obj-cacert <cert_path>

      Specifies a CA certificate that will be used to verify the identity of the object store being connected to.

      --obj-endpoint <endpoint>

      The host/address of your object store.

      --obj-no-ssl-verify

      Skips the SSL verification phase when connecting to the object store. Specifying this flag will allow a connection using SSL encryption, but you are vulnerable to a man-in-the-middle attack.

      --obj-region <region>

      The region in which your bucket/container resides. For AWS this option may be omitted when using the shared config functionality. See the AWS section of the cloud documentation for more information.

      --obj-secret-access-key <secret_access_key>

      The secret access key which has access to you chosen object store. This option can be omitted when using the shared config functionality provided by your chosen object store. Can alternatively be provided using the CB_OBJSTORE_SECRET_ACCESS_KEY environment variable.

      When using AWS, this option expects a secret access key. See https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys for more information.

      When using Azure, this option expects an account key. See https://docs.microsoft.com/en-us/azure/storage/common/storage-account-keys-manage?tabs=azure-portal for more information.

      When using GCP, this option expects a client secret. See https://cloud.google.com/storage/docs/authentication for more information.

      --obj-log-level <level>

      Set the log level for the cloud providers SDK. By default logging will be disabled. Valid options are cloud provider specific and are listed below.

      The valid options for the AWS SDK are debug, debug-with-signing, debug-with-body, debug-with-request-retries, debug-with-request-errors, and debug-with-event-stream-body.

      The valid options for the Azure SDK are info, debug, debug-with-request-retries and debug-with-request-retries-and-lro.

      The Google Storage SDK does not expose advanced logging configuration meaning this option is explicitly ignored, however, this behavior may change in the future.

      --obj-auth-by-instance-metadata

      Depending on the cloud provider, using instance metadata for authentication is disabled by default. Supplying this flag will allow the fetching credentials/auth tokens from (VM) internal instance metadata endpoints.

      By default, this option is disabled for AWS.

      By default, this option is enabled for Azure.

      By default, this option is enabled for GCP.

      --obj-auth-file

      GCP offers the ability to use a file which contains credentials which will be used to perform authentication. The --obj-auth-file flag accepts a path to an authentication file. This flag is unsupported for the AWS/Azure cloud providers.

      --obj-refresh-token

      GCP requires a refresh token when using static credentials, this will be used to refresh oauth2 tokens when accessing remote storage.

      AWS S3 Options

      Optional
      --s3-force-path-style

      By default the updated virtual style paths will be used when interfacing with AWS S3. This option will force the AWS SDK to use the alternative path style URLs which are often required by S3 compatible object stores.

      START AND END

      This sub-command accepts a --start and --end flag. These flags accept multiple values to allow you to flexibly operate on a range of backups.

      Indexes

      Indexes may be supplied to operate on a range of backups, for example --start 1 --end 2 will include start at the first backup and will finish with the second backup. Note that the first backup is 1 and not 0 and that the --end flag is inclusive.

      Short Dates

      Short dates may be supplied in the format day-month-year. For example --start 01-08-2020 --end 31-08-2020 will operate on all the backups which were taken during August of 2020. Note that the end date is inclusive.

      When supplying short dates, you may supply start or oldest as a placeholder for the date on which the first backup in this repository was taken. The keywords end or latest may be used as a placeholder for the date last backup in the repository was taken.

      Backup Names

      Backup names may be supplied as they exist on disk. For example --start 2020-08-13T20_01_08.894226137+01_00 --end 2020-08-13T20_01_12.348300092+01_00 will cause the sub-command to operate on all the backups which inclusively fall between these two backups.

      When supplying backup names, you may supply start or oldest as a placeholder for the first backup in the repository. The keywords end or latest may be used as a placeholder for the final backup in the repository.

      EXAMPLES

      The remove command is used to remove a backup repository from disk. Below is an example of how to run the remove command. The /data/backup directory is used as the archive directory and the backup repository is named "example".

      $ cbbackupmgr info --archive /data/backups --repo example --all

      We can delete the first two backups using indices range such as 1,2:

      $ cbbackupmgr remove -a ~/backup_repo -r example --backups 1,2
Backup `2019-09-18T11_13_58.136188+01_00` deleted successfully from archive `/Users/carlosbetancourt/backup_repo` repository `example`
Backup `2019-09-19T11_14_29.026324+01_00` deleted successfully from archive `/Users/carlosbetancourt/backup_repo` repository `example`
All backups in range `1,2` were deleted

      To delete only backup 2019-09-19T11_14_29.026324+01_0 we can do as follows:

      $ cbbackupmgr remove -a ~/backup_repo -r example --backups 2019-09-19T11_14_29.026324+01_0
Backup `2019-09-19T11_14_29.026324+01_00` deleted successfully from archive `/Users/carlosbetancourt/backup_repo` repository `example`

      To delete backups between the 18-09-2019 and 19-09-2019 we can do as follows:

      $ cbbackupmgr remove -a ~/backup_repo -r example --backups 18-09-2019,19-09-2019
Backup `2019-09-18T11_13_58.136188+01_00` deleted successfully from archive `/Users/carlosbetancourt/backup_repo` repository `example`
Backup `2019-09-19T11_14_29.026324+01_00` deleted successfully from archive `/Users/carlosbetancourt/backup_repo` repository `example`
Backup `2019-09-19T11_14_40.410627+01_00` deleted successfully from archive `/Users/carlosbetancourt/backup_repo` repository `example`
Backup `2019-09-19T11_14_29.026324+01_00` deleted successfully from archive `/Users/carlosbetancourt/backup_repo` repository `example`
All backups in range `18-09-2019,18-09-2019` were deleted

      Finally, we can also provide exact backup archive name ranges such as 2019-09-18T11_13_58.136188+01_00,2019-09-19T11_14_29.026324+01_00.

      $ cbbackupmgr remove -a ~/backup_repo -r example --backups 2019-09-18T11_13_58.136188+01_00,2019-09-19T11_14_29.026324+01_00
Backup `2019-09-18T11_13_58.136188+01_00` deleted successfully from archive `/Users/carlosbetancourt/backup_repo` repository `example`
Backup `2019-09-19T11_14_29.026324+01_00` deleted successfully from archive `/Users/carlosbetancourt/backup_repo` repository `example`
All backups in range `2019-09-18T11_13_58.136188+01_00,2019-09-19T11_14_29.026324+01_00` were deleted

      Removing data that is stored in AWS S3 is very similar to removing a local repository/backup, below is an example command which remove a given backup:

      $ cbbackupmgr remove -a s3://storage/backup_archive -r backup_repo --obj-staging-dir ~/backup-archive --backups '2020-04-22T14_10_18.372643628+01_00'
Backup `2020-04-22T14_10_18.372643628+01_00` deleted successfully from archive `backup_archive` repository `backup_repo`

      DISCUSSION

      The remove command is used to safely remove a backup repository from an archive. This command is provided because only the cbbackupmgr utility should ever be used to access or modify a backup archive. Removing a backup repository will remove data permanently from disk. Data is not recoverable once it has been removed.

      ENVIRONMENT AND CONFIGURATION VARIABLES

      CB_ARCHIVE_PATH

      Specifies the path to the backup archive. If the archive path is supplied as a command line argument then this value is overridden.

      CB_OBJSTORE_STAGING_DIRECTORY

      Specifies the path to the staging directory. If the --obj-staging-dir argument is provided in the command line then this value is overridden.

      CB_OBJSTORE_REGION

      Specifies the object store region. If the --obj-region argument is provided in the command line then this value is overridden.

      CB_OBJSTORE_ACCESS_KEY_ID

      Specifies the object store access key id. If the --obj-access-key-id argument is provided in the command line this value is overridden.

      CB_OBJSTORE_SECRET_ACCESS_KEY

      Specifies the object store secret access key. If the --obj-secret-access-key argument is provided in the command line this value is overridden.

      CB_OBJSTORE_REFRESH_TOKEN

      Specifies the refresh token to use. If the --obj-refresh-token argument is provided in the command line, this value is overridden.

      CB_AWS_ENABLE_EC2_METADATA

      By default cbbackupmgr will disable fetching EC2 instance metadata. Setting this environment variable to true will allow the AWS SDK to fetch metadata from the EC2 instance endpoint.
