what backup should i use

After a full backup i want to schedule weekly a backup .i dont want to be depended on more then 2 files.as i know the incremental backup creates a new smaller file .my question is what are differences betwen incremental/differntial? i want a solution that the changes since the last full backup won't be dependable on too much files

You want to run differentials then. To restore using differentials you only need the most recent full backup and the most recent differential back to be back to where you were prior to your failure.

To answer your question about the difference between differential and incremental;

Differential is a partial backup that checks for differences compared to your latest full backup, while incremental compares to the the partial backups aswell.

So differential is what you are after.

so for differential restoration i wil need only the latest differential backup and the full backup?

oyvindha

That is correct :)

so i can delete old differential files?

oyvindha

Well that depends what your backup needs are. If you ever have the need to restore a file, but not to the latest version, you want to keep all version of the file.

Hope I understood your question correct.

for example so if i want to restore my pc for 2 days ago and my last differential file is from yesterday and my full backup file is from a month ago..and my system was damaged so how should i restore it in further that my windows will work smoothly

oyvindha

If that backup you did yesterday was the only one you had since the full backup, and you needed to atleast restore 2 days back.. you would have to roll back to the full backup.

the important issue for me is like that: i am doing differntial back every friday at 3am. if my pc crashes at saturday for example a hd failure. and i need all to be restored. what should i do? restore the full backup and then the only latest diffential backup? is in this case my winodows effectively will be restore to the most recent status?
