Portable back-up device
![Antonio Correia](https://us.v-cdn.net/6029383/uploads/customavatars/19/navatar_4919.jpeg)
I am planning to buy a Toshiba Canvio 3.0 Portable USB Hard Drive of 1 TB to use as back up device for all the photographs I have.
I do not intend to use DropBox or similar cloud service.
However, I would like to know if I can use it as a diff or else I will have to copy the files all the time, over and over.
I have been looking for this info but I have not seen it or I have missed it![:) :)](https://dgrin.com/resources/emoji/smile.png)
Do you have any experience with this kind of equipment ? Would you please share it with us all ?
Thank you

I do have another synchronising program to sync my work USB with a folder at home. Free program unless you are syncing a large number of files and then you have to buy a "pro" licence ... but that is not expensive. After the first run, this is also very quick.
Not sure if I'm allowed to say what programs they are but PM me and I can tell you.

Nice tip the one about the disadvantages ! Very important in fact. I had never thought about it myself.
Most probably I will go a simple (?) Ultra-portable drive which is supposed to allow me to have all the files everywhere I go.
You mean you are using diff, right
So, the best is probably "sacrifice" the drive and make integral copies every week or so. It is not the best of the Worlds but looks reasonable, don't you think so ?
Very quick and I am much more inclined to run backups more often than once a week.
For each of my backup jobs I have two external hard drive mirrors in my office; one always stays there whilst the other rotates with a third hard drive offsite. (hard drives are pretty cheap storage option - and I wait until there is a sale on!)
I generally run my main backup job at least once each week; and then about once per month, I rotate one of the drives with my offsite drive. So if my house burns down I will lose one month's photos at worst. Not perfect but has worked fine for me - keen amateur.

It is sufficient considering the two other drives I have.
Thank you all for the trouble writing text
For backup, I am not a big fan of incremental backups, as they tend to get messy and very very large. I prefer to do what I call a 'net new' backup. By this I mean I want to make sure that any new files are added to the backup disk, but anything not changed is left alone, And, I want any files on the backup drive but not on the main disk to be left alone (archive). In addition, any changed files get overwritten on the backup drive. This way, my backup is essentially a snapshot of my working drive, in addition to providing an archive ability.
I use two programs to help with this: Synctoy for Microsoft Windows, and Sychron for Mac. Both offer this capability, and both are free.
