arqinator
Cross-platform restoration of Arq backups. Download arqinator binaries from the releases page.
Please explicitly test listing directories and recovering files before assuming it will work for you.
Features
- Cross-platform support for Windows, Mac OS X, and Linux.
- Tested on Windows 7 32-bit, Mac OS X Yosemite 10.10.5 64-bit, and Ubuntu 14.04 LTS 64-bit
- Deployable as a single executable file, no external dependencies required.
- List all backup sets in a particular backup type using
list-backup-sets
- List the contents of directories or information about a file using
list-directory-contents
- Recover single files, sub-folders and their contents, or entire backup sets,
using
recover
Limitations
- Currently only supports the following backup types:
- S3
- Google Cloud Storage
- SFTP (only unencrypted SSH private keys)
- arqinator has been tested on backups created by Arq 4.14.5 only. I do not know if arqinator works on previous versions of Arq. I'm doubtful that arqinator will work on previous major versions of Arq (i.e. 3 or 2).
- Files are downloaded in serial, might take a while to recover a lot of data.
TODO
- soft links aren't supported
- do you want to 'chown' files and folders to the UID/GID backed up?
- maybe offer as an option?
- support multiple encryption passwords for multiple accounts
- maybe have a text-file based configuration?
- support all backup types possible with Arq, start with Dropbox.
- explicitly check SHA1 hashes of blobs to confirm no corruption.
- Files are downloaded in serial, should do it in parallel.
Testing done so far
I've successfully listed backup sets, listed directory contents, and downloaded specific files and subfolders on:
- Backups created by Mac OS X 10.10.5 onto S3, Google Cloud Storage, and SFTP, and then retrieved back onto the same Mac OS X host.
- Backups created by Windows 7 onto S3, and then retrieved back onto the same Windows 7 host and a different Ubuntu 14.04 host.
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
Download arqinator binaries from the releases page.
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.
SFTP
The preferred way of using SFTP is to use password-less SSH login by putting your
SSH public key into the SFTP server's authorized_keys
. When you do so
currently arqinator only supports unencrypted SSH private keys. However if
you want to log into the SFTP server using a plaintext password you can set
the following environment variable:
ARQ_SFTP_PASSWORD=my-sftp-password
2. List backup sets
Note that there will be a difference between how paths appear on Windows and Linux/Mac:
S3, Mac

3. List directory contents of backups
Again note that paths for Windows will look a little unusual.

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
