Hi all
Coming back to a topic I raised a few months ago. I've been trying to get a write-once-read-many backup using tape. Trouble is - it keeps failing. It's a fair old amount of data to backup (20+Tb) but I think one of the issues is I'm trying: tar czvf /dev/nst0 /path/to/data Googling tells me tar's max file size is 8Gb and my files to be backed up (which are highly compressed anyway) are all around 8Gb - hence even only 2 of them will create a tar file over 8Gb. I'm happy to remove the z so remove compression but is the way to this really (seems awfully clunky)_ to write a script to supply each file to be archived as the second argument to the command above. So my tapes will end up with 500 .tar files if I have 500 files to compress? Doing it as one .tar file - or even one .tar per directory is going to result in .tar files of over 200Gb so possibly the reason for the errors. If anyone's wondering what error codes I'm getting, it's usually "file too big" (I'm paraphrasing). Lastly - I've not found any decent GUI based (free) software to do this. Grsync didn't seem to like my tape drive - not sure why Cheers R
