BackUp External HDD in local network NAS

se flag

I have an external HDD that I want to automatically back-up daily in a NAS. The NAS is available through a local network.

My best guess for backing-up the drive is creating an image through the disk utility and saving it in the NAS. Is it the correct procedure? Are there any ways to automate this action in a scheduled manner?

Thank you all!

Image backup is not the best. It consumes lots of space and has to copy entire partition(s) each time, but does include any deleted files that rsync may not include. If external & automated, you must be sure it is always connected or you will have issues. https://help.ubuntu.com/community/rsync You can schedule in cron. https://help.ubuntu.com/community/CronHowto Does this drive have an install or just data? Does some data not change as often. You often can use rsync for media and rdiff for data that changes a lot. http://rdiff-backup.nongnu.org/examples.html

Thank you @oldfred for your answer. It is exactly what I need since a lot of data do not change often. Unfortunately, I tried to reach the NAS using SSH but it always refuses the connection, I can only write in it using the Files UI. Anyway, when I will solve this problem rdiff is what I need.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
