Key/Value Dump and Restore (KVDR)

Simple tool to dump and restore data from Key/Value (Redis like) databases.

# Requirements

• [redis-py](https://github.com/andymccurdy/redis-py)

• [docopt](https://github.com/docopt/docopt)

# Installation

For the time being (while kvdr is under active development) I am not going to bother to upload to PyPI, so the fastest way to install it is if you do the following:

# Create virtual environment python3 -m venv $HOME/.kvdr # Activate it . $HOME/.kvdr/bin/activate # Install kvdr, version 0.9.8 pip3 install git+https://gitlab.com/dejan/kvdr.git@0.9.8#egg=kvdr

In theory every useful change I made in kvdr is tagged with a new (semantic) version, so it may be that at the time you read this there were some newer releases, so please check the GitLab page.

Installation on Windows/[ReactOS](http://reactos.org) should be as straightforward. I suggest you try [MSYS2](https://www.msys2.org/). In MSYS2, with Python3 packages installed, the installation steps should be the same as above.

# How to use

Use kvdr or kvdr –help to see the list of available options. It should look something like:

KVDR - Key/Value Dump and Restore

Usage:

kvdr dump [–file=<file_name> | –screen] <redis_url> kvdr load (–file=<file_name>) [–dry-run] <redis_url> kvdr –dry-run kvdr (-h | –help) kvdr –version

Options:

-h –help Show this screen. –version Show version. –screen Dump to the console instead of file. –file=<file_name> A file where we store dumped Redis records. Default: “redis.dump” –dry-run A trial run. Works only for the loading operation.

Examples:

kvdr dump –file=redis13.backup redis://admin:BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC@localhost:6379/13 kvdr load –file=redis13.backup redis://:BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC@localhost:6379/3

## Data dump

redis-cli -h localhost -a BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC -n 13 < var/test-data.redis kvdr dump –file=redis-dump.txt redis://admin:BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC@localhost:6379/13

If you have just cloned the kvdr repository, but not installed anything, you can run it inside the working directory:

cd <path to the working directory> python3 -m venv $HOME/.kvdr # Activate it . $HOME/.kvdr/bin/activate PYTHONPATH=. python3 -m kvdr.kvdr dump –file=redis-dump.txt redis://admin:BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC@localhost:6379/13

## Data load

Load the redis.dump file data into the redis://localhost/3 database

# Let’s first delete all the data in the existing database: redis-cli -h localhost -a BABADEDAuikxWx0oPZYfPE3IXJ9BVlSC -n 3 | echo “flushdbnquit” # Load the data kvdr load –file=redis.dump redis://localhost/3

This does not work (yet):

kvdr load –dry-run –file=redis.dump file:///blah.dat

# Credits

[Andy McCurdy](https://github.com/andymccurdy) - for writing fantastic Python library for Redis.

# Future

• Add support for memcached

• Add support for DynamoDB

• Check whether kvdr works out-of-box with [KeyDB](https://keydb.dev/)

• Design an API so users can write Dumper/Loader implementations of their own.
