A Picasa Web Albums backup utility
(sudo) pip install backasa
The goal of this tool is to provide a minimal CLI backup/mirroring tool for Picasa Web Albums.
This will initiate or sync an existing backup of all picasa web albumns for this user, into /target/of/backup
backasa -e email@example.com -p password1 -t /target/of/backup/ backup
Setup - Setup backup directory and store your credentials
mkdir backup-target cd backup-target backasa setup
Backup - routinely run the backup (cron, etc..)
cd backup-target backasa backup
Cleanup - Remove old versions of files and deleted files
cd backup-target backasa cleanup

--password or -p
Manually provide password on the command line
--limit or -l

This is helpful if you want to gradually catch up your backups during off peak times
Ex. Cron job starts at 1 AM, using -l 4 it will stop ~ 5 AM
backasa will pick up where it left off for the next run
--target or -t

Built in help documentation
Backasa handles user authentication one of two ways, specified as command-line arguments (--email and --password), or via a .config file in the backup directory generated by the setup action. This .config file is stored with the same level of security as your private ssh keys.
If you are using Google 2-step Verification, you will need to create an application specific password for backasa and use it in your setup.
Manual Garbage Collection
By default Backasa does not delete files. As new file versions come in older versions are marked as .old and are left on the file system along side their newer counterparts. Files deleted from picasa are left as is in your backups. The cleanup action is used to remove old versions of files and scan picasa for deleted files to remove from your file system.
