Well I found a place that charges a very low fee for the service so I thought that it might be worth it just to not have to worry about making them myself.It's really up to you to decide if they are worth the price or not. If you are short on time then it might be worth it to you but if you have the time to make your own backups then it might not be worth the cost.
I personally like to make my own backups because I want to have more control over them and can take measures to ensure that they are not lost or damaged.
Do you remember the name of the place you used?I used one of these before and it was good for me because I did not have much time to do the backups I needed to do on a regular basis. It worked out nicely but now I just do them myself to cut my costs and because I have a little extra time nowadays.
