Please define a ?reliable verifiable backup??

Often I have observed warnings about editing the registry. With the suggestion of first obtaining a verifiable backup. How does one know that the backup will actually work? IE, the motherboard goes and an upgraded motherboard is required. Or the entire Mirror goes out, (ok it's not likely) and it impossible to purchase the same disks.

Are backup to tape with verification as one of the options really reliable?

Does the backup from one machine to another online disk always work?

Thanks for your advice in advance.

In a situation like you described, it is highly unlikely that you will be able to restore the server from the backup. You would have to creat it from scratch.

What is important is that you have the DATA from the server and can restore that. This is what is most important.

There are other things that are needed for a disaster recovery besides a reliable backup. You should have information available about every server so that if you have to rebuild the server with new hardware, you can loadall the applications and it's setting the same as the original and then just reload the data needed.

Hi,
First, Regedit is dangerous without a backup to restore the registry. Registry backups are done to floppy.
Second, A change of MB means your old registry is non functional unless the exact same MB is replaced.
Third, A change of MB usually means reinstalation if you change MB mfg.
Forth, If your data is that important, then use an off site backup source.
Fifth, If your "mirror" is on site than the backup of important data is usless in case of fire or lightning.
Sixth,nothing always works. "Murphy's Law"
Seventh, A verified tape backup is excelent if taken off site daily and verified outsource backups are also excelent.
Hope this helps.
