Usage:
br backup full [flags]
Flags:
-h, --help help for full
Global Flags:
--debug Output log in debug level or not
--log string Specify br detail log path (default "br.log")
--meta string Specify meta server
--s3.access_key string S3 Option: set access key id
--s3.endpoint string S3 Option: set the S3 endpoint URL, please specify the http or https scheme explicitly
--s3.region string S3 Option: set region or location to upload or download backup
--s3.secret_key string S3 Option: set secret key for access id
--spaces stringArray (EXPERIMENTAL)space names.
By this option, user can specify which spaces to backup. Now this feature is still experimental.
If not specified, will backup all spaces.
--storage string backup target url, format: <SCHEME>://<PATH>.
<SCHEME>: a string indicating which backend type. optional: local, s3.
now only s3-compatible is supported.
example:
for local - "local:///the/local/path/to/backup"
for s3 - "s3://example/url/to/the/backup"
