I'm taking backup of my database and it has text field which contains following content:

Original data: "Rock'n Roll"

Database backup: "Rock\'n Roll"

What it should be in backup: "Rock''n Roll"

So what could be causing this error in my MySQL configuration?

Unusable? Rock\'n Roll should be a perfectly valid form. Backslash is just an escape character telling MySQL that the following ' should be considered as data and not as SQL delimiter '.

Did you try actually restoring you backup?

And the error message is? – Janne Pikkarainen Jun 17 '11 at 9:12
It returns "Unknown object in backup file" error in target linux system. Itake backup from Windows 7 32bit system. – newbie Jun 17 '11 at 9:15
I tried to restore database in my Windows 7 and it worked, but exact same file gives that error in Linux. I use MySQL Admin over SSH to restore database in Linux. – newbie Jun 17 '11 at 9:21
Problem was in MySQL admin, when I used mysql from command line in linux it worked. – newbie Jun 17 '11 at 10:02
