Many server administrators have to face the problem of backing up their files when creating their architecture. This is a very important activity, because if something goes wrong, you can quickly restore your system to its pre-crash state with such files. The simplest tools for making basic backups are tar, gzip and lftp. The first application creates a package with the required files, the second one compresses it, and the third one sends to an external server, designed for such copies. Of course, some people can also add data encryption within maximum security.<\/p>\n\n\n\n\n\n\n\n
However, after some time, it turns out that these backups are becoming larger and larger, so they take up a lot of space, take a long time and send too much time to other machines. What can we do about it? Look for a tool that will enable us to create incremental backups.<\/p>\n\n\n\n
And here appears Duplicity. It is an application for backing up selected directories in the form of encrypted files and then saving them in some location (both remote and local). It uses the rsync library, which allows you to easily create incremental archives that store only the changed data of some files. Archives can be encrypted and transmitted remotely to another server, using protocols such as: FTP, IMAP, RSYNC, S3, SSH\/SCP, WEBDAV and many others.<\/p>\n\n\n\n
