Usage of drawback, disadvantage

[Attila]

Hi All,

I want to tell a user that if he has the possibility he should make a copy of the database file before he makes the changes.

Which is the best sentence?

- It isn't a drawback to make a backup
- It isn't a disadvantage to make a backup
- It will do you good to make a backup

BAD
- It isn't a drawback to make a backup.
- It isn't a disadvantage to make a backup.
- It will do you good to make a backup.
There's nothing wrong with the grammar of these; they just contain inappropriate usage.

GOOD
- You should make a backup.
- You'd better make a backup.
- You'd be better off making a backup.
- You'd best make a backup.
- It's good to make a backup.
etc.
