Q: I have a discussion on another forum about backups. I have a backup my ~ 60GB of data using tar and gzip. He said he would be Norton Ghost, have used that I did not. For me, tar and gzip are as good if not better, and they came free with Debian.
He think that I take a risk using gzip.
So what do you think? Im not trying to slam him or anything, he could be right, but the way I look at:
1. tar and gzip stapling the community.
2. Thousands (if not more) of people use them everyday.
3. A tar.gz file is readable by virtually any computer.
4. tar and gzip free.
So what do you think? How do you back up your stuff?
How to Hunt Ghosts
Re:I personally like to just copy files over to a CD. I know that using Bzip2 would help a lot specially with text files. But I don't want to take the chance of compressing something and then loossing all the files. For example if one of the files that you are compressing is corrupted or gets corrupted then all the files in the archive would also get corrupted because the program wouldn't be able to uncompress them all.

Re:Data corruption with gzip.
I may have only been in the *nix comminity for 7 years, but I've never seen a corrupt gzip file.
You have the exact same chances of corruption with Ghost.

you can also set this up to do incremental backups do disk (i.e. 3TB of IDE drive…) as well as tape.

Re:I have seen a corrupt tar.gz file but I can't say if it was caused by gzip or not. Ghost works fine for doing the whole machine or a partition but you have to reboot the machine to use Ghost. Your method is much better. There are entire backup programs built on using gz, I wouldn't worry about it. If I used *nix more I would be using gz for sure to do backups.

Re:will a couple of bit errors in a gzipped file cause you to lose the whole thing? Could he be thinking of that (whether or not it's true)?

I've never seen one I would blame on gzip.
