Upload Backintime snapshots to AWS S3.
Back In Time is a simple backup tool for Linux, which saves your backups as normal directories on external disks or remote servers. With bits3 you can save Back In Time backups as archive on AWS S3.
The Back In Time backup directory will be packed as a tar, encrypted with a password via the Linux tool GnuPG and uploaded to AWS S3 via the official AWS SDK for Python (boto3).
This process will take a few hours for large backup directories. Thus bits3 is not for daily backup purpose, rather for creating emergency backups every few months, which can be used, if all other backups are lost.
Python3.6 or greater is required.
pip install bits3
You have to create a new AWS bucket first. For each backup directory you have to use a dedicated bucket!
The handling of the AWS credential is the same as in the official AWS CLI. You can use environment variables or a credentials file. Check the official documentation for more information (https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html).
bits3 --progress --bucket <AWS_BUCKET_NAME> --secret <PASWORD_FOR_ENCRYPTION> <BACKINTIME_BACKUP_DIR>
<AWS_BUCKET_NAME> and <PASWORD_FOR_ENCRYPTION> can also be provided via environment variables:
export BITS3_BUCKET=<AWS_BUCKET_NAME> export BITS3_SECRET=<PASWORD_FOR_ENCRYPTION> bits3 <BACKINTIME_BACKUP_DIR>
There are some more options avaialbe, check the help to get more information:
