This is the second part of the article How To Backup Your Files Using Deja Dup [Ubuntu]. If you have not read the first part, I suggest that you do so.
In the first part, we discussed how to install Deja Dup and how to set up the storage location and the select the folders to be backed up. Now we continue with how you can set up the backup schedules.
After setting up the folders to back up, we have the most important part – scheduling the backup. Deja Dup allows you to take backups either manually or automatically. If you want to take backups manually, uncheck the box next to Automatically back up on a regular schedule. It is, however, recommended that you allow Deja Dup to take backups automatically.
If you choose to let Deja Dup take up the backups automatically, pick how often Deja Dup will back up. A daily backup could be quite tedious. So, I recommend the weekly backup unless you have critical data. The next fieldKeep backups is very important. We want to keep enough backups in case something goes wrong. But at the same time keeping backups for a very long time can take up a lot of disk space unnecessarily. For a weekly backup schedule, keeping the backups for a month or two is sufficient. Keeping the backups forever is not recommended as very old backups will become obsolete.
Once you have set up Deja Dup to take backups automatically, you do not need to do anything except when you have to restore a backup. If you choose to do a manual backup though, you have to launch the application Deja Dup Backup Tool every time you want to take a backup and click on Back Up. Remember that taking backups will take time and in Ubuntu 11.04, the progress is shown in the launcher.
Restoring files using Deja Dup is incredibly easy. Open the Deja Dup Backup Tool and click on Restore. Now you have to select the location where the backup files are located. Make sure to check the box next to Backup files are encrypted if you encrypted them as recommended. After you have selected the backup location, you can choose which backup to restore and if you want to restore in the original location or to another location. Select your chose and Deja Dup will start the restoration. Depending to the size of the backups, it could take a while to complete the restoration.
Deja Dup Vs Other Backup Tools
Deja Dup is by no means the most powerful backup tool available for Ubuntu. However, the advantage that Deja Dup have over the other backup tools is its simplicity. Deja Dup is so simple to use that anyone who can operate a computer will be able to use it. Yes, Deja Dup lacks certain features such as restoring a single file etc. But it has most of the features that a normal user would expect from a backup tool.
As mentioned in the first paragraph, Deja Dup will be included as a default application in Ubuntu 11.10 “Oneiric Ocelot”. In the earlier Ubuntu releases too, I consider Deja Dup as a must have application.
