s3v 0.1.1

Convenient CLI tool to work with versioned (including Object Lock) S3 buckets (recover, undelete, etc.)

s3v

Convinient CLI tool to work with versioned S3 buckets. Like aws s3 or aws s3api but much easier to use.

Installation

# recommended
pipx install s3v

# or from git
pipx install git+https://github.com/yaroslaff/s3v

Configuration

s3v uses boto3, so configuration is same as for aws utility (same ~/.aws/ files or AWS_ shell variables, and optional --profile NAME argument)

Examples

We upload three versions of same file, each one will overwrite old copy.

Upload

$ echo 1 > test.txt 
$ s3v cp test.txt s3://stg-objectlock/s3v/
$ echo 2 > test.txt 
$ s3v cp test.txt s3://stg-objectlock/s3v/
$ echo 3 > test.txt 
$ s3v cp test.txt s3://stg-objectlock/s3v/

You can also give full target name like s3://stg-objectlock/s3v/test.txt. s3:// prefix is optional (s3 will try to guess what is local file and what is bucket name).

List

Now, list contents of s3v logical 'folder' (all objects with name starting with s3v/). In "ls" we see filename, last modification time, size of latest copy and number of versions in storage. If we give full name of object, ls will list all versions of this object.

$ s3v ls stg-objectlock/s3v
Listing objects in bucket 'stg-objectlock' with prefix 's3v'
test.txt                                |2026-02-10 16:21:55|              2|   3|

$ s3v ls stg-objectlock/s3v/test.txt
Listing objects in bucket 'stg-objectlock' with prefix 's3v/test.txt'
Objects under prefix 's3v/test.txt':
s3v/test.txt

Downloading

s3v cp will download latest version of file.

$ s3v cp stg-objectlock/s3v/test.txt .

$ cat test.txt 
3

Give -s VERSION to download specific version.

$ s3v cp stg-objectlock/s3v/test.txt . -s by0fQCa9Jl7gFgl8vKEjaDvl8z3CSRnD
  Using version: by0fQCa9Jl7gFgl8vKEjaDvl8z3CSRnD
$ cat test.txt 
1

Delete and undelete

s3v rm deletes file. After deletion, aws s3 ls do not list file, but s3v ls still shows it with [DEL] tag.

$ s3v rm stg-objectlock/s3v/test.txt
$ aws s3 ls stg-objectlock/s3v/
$ s3v ls stg-objectlock/s3v/
Listing objects in bucket 'stg-objectlock' with prefix 's3v/'
test.txt                                |2026-02-10 16:35:00|              2|   4| [DEL]

If we will see versions for file, we will see special delete marker on S3 (which makes file to be logically 'deleted').

 $ s3v ls stg-objectlock/s3v/test.txt
Listing objects in bucket 'stg-objectlock' with prefix 's3v/test.txt'
# Fetching version metadata for bucket: stg-objectlock...
# Fetched metadata for 215 versions from 153 object(s) in bucket 'stg-objectlock'
Objects under prefix 's3v/test.txt':
s3v/test.txt [deleted]

s3v unrm will remove "delete marker" and file (latest version) will be available again.

$ s3v unrm stg-objectlock/s3v/test.txt

$ s3v ls stg-objectlock/s3v/
Listing objects in bucket 'stg-objectlock' with prefix 's3v/'
test.txt                                |2026-02-10 16:35:00|              2|   3|

Restore specific version

To recover specific version of file (make it to be current) use s3v recover (or just s3v r). Let's recover first version of file.

$ s3v recover stg-objectlock/s3v/test.txt . -s by0fQCa9Jl7gFgl8vKEjaDvl8z3CSRnD
Successfully recovered version by0fQCa9Jl7gFgl8vKEjaDvl8z3CSRnD as current version of s3://stg-objectlock/s3v/test.txt

$ s3v cp stg-objectlock/s3v/test.txt . 
$ cat test.txt
