Tar and hard links.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I have a small backup system running which basically uses rsync with the --link-dest= option which basically creates hard links to unchanged files..

For anyone interested this means that I am able to backup 950MB over 6 days and only use 1.3GB (instead of the nearly 4GB it would take with a straight copy) of disk space.. :)

Anyway, I now need to backup the 6 days worth of daily backups (along with other data) to a tape and I will be using tar.. I don't want to have to backup the full volume of 4GB if there is a way to backup the hard links and so save space on the tape..

How does tar handle hard links?? Is there a switch to use or does it handle them automatically??

I looked through the man page and only saw a reference to symlinks but not hard links..
