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.
-
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 theobj-staging-dir
. SeeDisk 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
, anddebug-with-event-stream-body
.The valid options for the Azure SDK are
info
,debug
,debug-with-request-retries
anddebug-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.
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 Name | Size | # Backups | example | 4.38MB | 3 | + Backup | Size | Type | Source | Cluster UUID | Range | Events | Aliases | Complete | + 2020-06-02T07_49_11.281004+01_00 | 1.69MB | FULL | http://localhost:8091 | c044f5eeb1dc16d0cd49dac29074b5f9 | N/A | 0 | 1 | true | - Bucket | Size | Items | Mutations | Tombstones | Views | FTS | Indexes | CBAS | - example | 1.69MB | 4096 | 4096 | 0 | 0 | 0 | 0 | 0 | + Backup | Size | Type | Source | Cluster UUID | Range | Events | Aliases | Complete | + 2020-06-03T07_49_52.577901+01_00 | 1.34MB | INCR | http://localhost:8091 | c044f5eeb1dc16d0cd49dac29074b5f9 | N/A | 0 | 1 | true | - Bucket | Size | Items | Mutations | Tombstones | Views | FTS | Indexes | CBAS | - example | 1.34MB | 2048 | 2048 | 0 | 0 | 0 | 0 | 0 | + Backup | Size | Type | Source | Cluster UUID | Range | Events | Aliases | Complete | + 2020-06-04T07_50_06.908787+01_00 | 1.34MB | INCR | http://localhost:8091 | c044f5eeb1dc16d0cd49dac29074b5f9 | N/A | 0 | 1 | true | - Bucket | Size | Items | Mutations | Tombstones | Views | FTS | Indexes | CBAS | - example | 1.34MB | 2048 | 2048 | 0 | 0 | 0 | 0 | 0 | $ cbbackupmgr remove -a /data/backup -r example Backup repository `example` deleted successfully from archive `/tmp/backup` $ cbbackupmgr info -a ~/data/backups --all Name | UUID | Size | # Repos | backups | 0db3337c-96b0-4b3a-a7fb-bbfd53790e5f | 0B | 0 |
The remove command can also be used to remove backups from inside a repository given the following archive:
$ cbbackupmgr info -a /data/backup -r example Name | Size | # Backups | example | 36.01MB | 3 | + Backup | Size | Type | Source | Range | Events | Aliases | Complete | + 2019-09-18T11_13_58.136188+01_00 | 12.00MB | FULL | http://localhost:8091 | N/A | 0 | 1 | true | + 2019-09-19T11_14_29.026324+01_00 | 12.00MB | INCR | http://localhost:8091 | N/A | 0 | 1 | true | + 2019-09-19T11_14_40.410627+01_00 | 12.00MB | INCR | http://localhost:8091 | N/A | 0 | 1 | true | + 2019-09-20T11_14_43.410627+01_00 | 12.00MB | INCR | http://localhost:8091 | N/A | 0 | 1 | true |
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.
