arqinator
Cross-platform restoration of Arq backups.
This utility is not production ready. Please explicitly test it before assuming it will work for you.
Getting started
0. Prerequisites
How to set environment variables on:
- Linux: https://www.digitalocean.com/community/tutorials/how-to-read-and-set-environmental-and-shell-variables-on-a-linux-vps
- Mac OS X: http://apple.stackexchange.com/questions/106778/how-do-i-set-environment-variables-on-os-x
- Windows: https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/sysdm_advancd_environmnt_addchange_variable.mspx?mfr=true
1. Configure Credentials
For all backup methods, set the following environment variable to the password you're using for encrypting your Arq backups:
ARQ_ENCRYPTION_PASSWORD=mysecretpassword
Only Arq backup sets encrypted by this password will be visible to you when you
run list-backup-sets. If the password is incorrect they will appear to be
invisible. Run with --verbose if you want more information.
S3
Set the following environment variables depending on which backup method you are using:
AWS_ACCESS_KEY_ID=AKID1234567890
AWS_SECRET_ACCESS_KEY=MY-SECRET-KEY
Google Cloud Storage
- Go to the Google Developers Console: https://console.developers.google.com//project/_/apiui/credential
- Download a JSON private key file using: https://goo.gl/SK5Rb7
- To determine your project ID, click on the gear in the top right, and click "Project information"
- To determine your bucket name, on the left navigation pane go to Storage - Cloud Storage - Browser, then find your bucket.
2. List backup sets
Note that there will be a difference between how paths appear on Windows and Linux/Mac:
S3, Mac
$ arqinator \
--backup-type s3 \
--s3-region us-west-2 \
--s3-bucket-name arq-akiajmthnhpkz2ixzrxq-us-west-2 \
list-backup-sets
ArqBackupSet

3. List directory contents of backups
Again note that paths for Windows will look a little unusual.
S3, Mac
$ arqinator \
--backup-type s3 \
--s3-region us-west-2 \
--s3-bucket-name arq-akiajmthnhpkz2ixzrxq-us-west-2 \
list-directory-contents \
--backup-set-uuid 98DB38F8-B9C6-4296-9385-3C1BF858ED5D \
--folder-uuid 8D4FAD2A-9E08-46F7-829D-E9601A65455D \

4. Restore
You can restore either individual files or entire folders. Note that you need to use a Linux-like directory path for Windows backups:
S3, Mac, recovering a single file
$ arqinator \
--backup-type s3 \
--s3-region us-west-2 \
--s3-bucket-name arq-akiajmthnhpkz2ixzrxq-us-west-2 \
recover \
--backup-set-uuid 98DB38F8-B9C6-4296-9385-3C1BF858ED5D \
--folder-uuid 8D4FAD2A-9E08-46F7-829D-E9601A65455D \
--source-path /Users/ai/output.txt \
--destination-path /Users/ai/temp/output.txt
S3, Windows, recovering an entire folder in verbose mode
arqinator ^
--backup-type s3 ^
--s3-region us-west-2 ^
--s3-bucket-name arq-akiajmthnhpkz2ixzrxq-us-west-2 ^
--verbose ^
recover ^
--backup-set-uuid E7CFDEED-AB08-4970-A377-78F8313AC39C ^
--folder-uuid FE8BE3EE-B63B-4D1F-A7E9-6707297823B5 ^
--source-path /C/Users/username/Downloads/apsw-3.7.15.1-r1/tools ^
--destination-path /C/temp/tools
Google Cloud Storage, Mac, recovering a single file
$ arqinator \
--backup-type googlecloudstorage \
--gcs-json-private-key-filepath /Users/ai/keys/gcs.json \
--gcs-project-id midyear-courage-109219 \
--gcs-bucket-name arq-560729839528 \
recover \
--backup-set-uuid 7FE8D069-B218-4E17-8E58-0C7FAF8CFAFC \
--folder-uuid E6F4BC5E-B21F-4828-ADCC-8521F9DBC4C9 \
--source-path /Users/ai/temp/apsw-3.7.15.1-r1/PKG-INFO \
--destination-path /Users/ai/temp/PKG-INFO
TODO
- soft links
- do you want to 'chown' files and folders to the UID/GID backed up?
- support multiple encryption passwords for multiple accounts
- maybe have a text-file based configuration?
- support all backup types possible with Arq, start with SFTP.
- explicitly check SHA1 hashes of blobs to confirm no corruption.
Bugs
- Implement un-cached get, so that we can get the latest SHA from the master commit without having to delete the cache.
