EXAMPLES:
|
|
1. Enable versioning on bucket "mybucket" for alias "myminio".
|
|
{{.Prompt}} {{.HelpName}} myminio/mybucket
|
|
|
|
2. Enable versioning on bucket "mybucket" while excluding versioning on a few select prefixes.
|
|
{{.Prompt}} {{.HelpName}} myminio/mybucket --excluded-prefixes "app1/*/_temporary/,app2/*/_staging/"
|
|
|
|
3. Enable versioning on bucket "mybucket" while excluding versioning on a few select prefixes and all folders.
|
|
Note: this is useful on buckets used with Spark/Hadoop workloads.
|
|
{{.Prompt}} {{.HelpName}} myminio/mybucket --excluded-prefixes "app1/*/_temporary/,app2/*/_staging/" --exclude-folders
