spare 0.1.3

Description

This tool is used at Seantis to create backups stored on various S3 compatible services using a very limited subset of S3 commands.

This is what you need to know:

• Spare should not be used in production yet! Use at your own risk.

• Buckets should be managed by spare exclusively, other files are deleted!

• Each hostname must have a separate bucket for each backed up path.

• Spare stores exactly one copy of your data.

• Files are compressed using LZMA and encrypted on the client using AES-SIV.

• During upload, spare is limited to one core and less than 100MiB of memory.

• Duplicated files are stored only once.

• If you forget your password, you cannot restore your files.

• Spare is meant to be used with configuration management, the cli is minimal.

• Python 3.6.2+ is required.

Usage

To install spare:

pip install spare

To set the connection parameters:

export SPARE_ENDPOINT=host
export SPARE_ACCESS_KEY=access-key
export SPARE_SECRET_KEY=secret-key

To backup a folder:

spare create --password my-password --bucket my-bucket --path /my-path

To restore a backup:

spare restore --password my-password --bucket my-bucket --path /my-path

To verify the backup (downloads everything!):

spare verify --password my-password --bucket my-bucket --path /my-path

Run the Tests

Spare uses Minio <https://www.minio.io> to run tests against a real object storage server. As a result it can take a bit for the first test run to complete, as Minio is downloaded and stored in the pytest cache directory:

pip install -e '.[test]'
py.test
