In this example, an external USB hard drive called SILVERXHD (for Silver eXternal Hard Drive) is plugged into the Linux computer. If you can write to it, then so can rsync. Old files on the destination that have been deleted from the source will remain on the backup copy. To make a backup copy of your data to an external hard drive, the hard drive must be mounted and accessible to you. This option takes a directory as argument. Older files will not overwrite newer files. To implement our backup strategy we will make use of the -link-dest option of rsync. This will make a backup where the destination contains the latest versions of the files. Recommendations: I check Skip Newer and leave other options alone. After this operation, the destination will contain all the newer files, whether the newer file existed on the source or on the destination. But files that exist on the source but don’t exist on the destination will be copied. So if there is a destination file that is newer than the source file, the older source file will not be copied over top the newer destination file. ![]() Skip newer: Do not copy an old file on the source over a newer file on the destination. As an example, if you modify some documents on the source drive and/or on the destination, they will not be copied. The old files remain unchanged on the destination. Ignore existing: Do not copy files that are already exist on the source and destination drive, even if the file on the source is newer. If you accidentally delete a file or folder from the source but you have a copy on the destination, after this operation those files will be deleted from the destination. Files that were copied to the destination in an earlier backup but later deleted from the source will remain on the backup copy.ĭelete on destination: This is identical to the above option except the extra files that exist on the destination but not on the source will be deleted. command and add the following while specifying the actual full path to your script files. So if you never edit the files on the destination, this option (no option selected) will keep all your files up to date. You can create a cronjob to call the daily, weekly, and monthly backup scripts. Extra files that are on the destination that do not exist on the source are left alone. All other files are copied to the destination even if the destination files are newer. ![]() No option selected: Files that are identical on the source and the destination are not copied. I set up two test directories one on the source and one on the destination and tested the options.
