Sudo apt-get install duplicity duply python-botoĬreate a profile. # Replace 'precise' with your Ubuntu version's codename. If not, you can just install an older version of Duplicity from the distribution’s repositories. If you’re on Ubuntu, you should add the Duplicity PPA so that you get the latest version. It keeps your settings in a profile, and supports pre- and post-execution scripts. Luckily there is a tool which simplifies Duplicity even further: Duply. It has many options - too many if you’re just starting out. Setting up Duplicity and S3 using Duplyĭuplicity in itself is still a relative pain to use. Using encryption means that I don’t have to trust my service provider. This makes Duplicity and S3 the perfect combination for backing up my servers. Many hosting providers these days allow more than 1 TB of traffic per month per server. The current price for the US-west-2 region is only $0.09 per GB per month.īandwidth costs have also lowered tremendously. On the storage side, Amazon has consistently lowered the prices of S3 over the past few years. Duplicity works without needing special software on the remote machine and supports many storage methods, for example FTP, SSH, and even S3. This makes it impossible to use rdiff-backup to backup to storage services that don’t allow running arbitrary software.īen later created Duplicity, which is like rdiff-backup but encrypts everything. However, rdiff-backup has one drawback: you have to install it on the remote server as well. Rdiff-backup stores past versions as well and allows easy rollback to a point in time. Rdiff-backup also saves metadata such as permissions, owner and group IDs, ACLs, etc. Of the changed files, rsync is smart enough to only transfer the parts of the files that have changed!Īt some point, Ben Escoto authored the tool rdiff-backup, an incremental backup tool which uses an rsync-like algorithm to create filesystem backups. If you have a directory with 10 GB of files, and your remote machine has an older version of that directory, then rsync only transfers new files or changed files. The cool thing about rsync is that it only transfers changes. What is rsync? It is a tool for synchronizing files between machines. This is achieved by using the rsync algorithm. “Incremental” means that each backup only stores data that has changed since the last backup run. And finally, do you trust that the storage provider will not read or tamper with your data?ĭuplicity is a tool for creating incremental, encrypted backups.Until a few years ago, bandwidth was relatively expensive, making backing up the entire harddisk to a remote storage service an unviable option for those with a tight budget.Backup services provided by the hosting provider can be expensive.a fire) will destroy your backup as well. Furthermore, if your backup device resides on the same location where the data center is, then destruction of the data center (e.g. Buying or renting another harddisk from the hosting provider can be expensive. Most people can’t go to the data center and attach a hard disk.I don’t have to worry that my backup rules missed an important file.īacking up desktops and laptops is easy and cheap enough. ![]() I don’t have to worry about losing my data anymore. Backing up everything not only makes backing up a mindless and trivial task, it also makes me feel safe. Time Machine - Apple’s backup software - taught me to stop worrying about efficiency. However, this made setting up backups a total pain, and makes it very easy to procrastinate backups… until it is too late. I tended to tweak my backup software and rules to be as efficient as possible. I only want to backup things that need backing up. ![]() Because of this, I tend to worry about the efficiency of my backups. Backing up my entire harddisk would have costed me hundreds of dollars and hours of time. I still remember the days when a 2.5 GB harddisk was considered large, and when I had to spent a few hours splitting MP3 files and putting them on 20 floppy disks to transfer them between computers. I worry about the bandwidth and/or storage costs.I have to remember to run the backup on a periodic basis.I have to think about where to backup to.The thought of setting up backups always raised a mental barrier for me for a number of reasons: Backups are one of those things that are important, but that a lot of people don’t do.
