Installing on Amazon Linux AMI (release 2014.09)
Installing using yum. By default Amazon Linux AMI release has only AWS's yum repos, but it has EPEL (Extra Packages for Enterprise Linux) predefined but not enabled. To temporarily enable the EPEL 6 repository, use the yum command line option --enablerepo=epel.
Installing duplicity and dependencies:
sudo yum install duplicity rsync gpg python python-devel python-pip --enablerepo=epel
Insalling duply manually (latest version can be found here):
cd ~
wget http://downloads.sourceforge.net/project/ftplicity/duply%20%28simple%20duplicity%29/1.9.x/duply_1.9.1.tgz
tar -zxvf ./duply_1.9.1.tgz
sudo cp ./duply_1.9.1/duply /usr/bin/
rm -r ./duply_1.9.1
Install boto for S3 support:
sudo pip install boto
Test duply:
duply -v
This command should output something like:
duply version 1.9.1
(http://duply.net)
Using installed duplicity version 0.6.22, python 2.6.9, gpg 2.0.25 (Home: ~/.gnupg), awk 'GNU Awk 3.1.7', bash '4.1.2(1)-release (x86_64-redhat-linux-gnu)'.
To create backup profile (ex. www) use
duply www create
Edit default configuration (/home/ec2-user/.duply/www/conf)
vi /home/ec2-user/.duply/www/conf
conf file is pretty well documented, read it!
To use simple password protection comment line:
#GPG_KEY='_KEY_ID_'
And enter your password here:
GPG_PW='MYSUPERPASSWORD'
Set S3 bucket as a backup target:
TARGET='s3://s3-region.amazonaws.com/mybucket/some/sub/folder/'
#ex.:
TARGET='s3://s3-eu-west-1.amazonaws.com/mybackups/www/'
S3 Access Key ID gose here:
TARGET_USER='FEGAIKGR4OLIFF2UIP34'
S3 Secret Access Key gose here:
TARGET_PASS='aAezgEBvz6i34df0AHRTagNTS3wMT4w5np55eEDD'
Directory to backup:
SOURCE='/var/www/'
Set backup's max age (Used for the "purge" command.):
MAX_AGE=6M
Save and exit!
Run backup:
duply www backup
crontab -e
And add (newline at the end is requiered):
# Daily Backups @ 5 am
0 5 * * * duply www backup
To be quiet:
# Daily Backups @ 5 am (quiet)
0 5 * * * duply www backup > /dev/null 2>&1
I am getting "UnsupportedBackendScheme: scheme not supported in url: s3://". Though I have confirmed I have the URL format for my buckets region correct. Has anyone else seen that issue?
UnsupportedBackendScheme: scheme not supported in url: s3://s3-us-east-2.amazonaws.com/pinknose1/backup/www/
Update - I am very new to Linux so I wanted to update this in case any others run into the same issue. The workaround for me was to simply re-create the EC2 instance I was building this on. The url structure was actually fine, however at some point one or more of the fixes I had tried to apply had corrupted my duplicity install. A fresh install resolved this issue.
