Hi Ben, Hardlinking means that if tar is reading the data from a certain hardlinked file it will pack that data even if it's coming from another file. This means that when packing the numerous vs's on your system you must be sure to copy no hard linked files. Even if you would have the space to store this data it would be almost impossible to restore a broken system, because you don't have hard links packed in your tar archives, but real files. For as far as I've seen the FreeVSD system (I am fairly new to it :-) it has only a certain number of directories that are writable by a vs owner. This means you can easily filter the user data from the skel/hardlinked data and make a restorable backup of all your vs's.

A question that Ive just thought of - if u were to do a backup of say /home/vsd/* using programs such as 'dump' and 'tar', are they likely to handle hard linked files efficiently? For example, if u have a file X in 1 skel, and 100 VSs use that skel and hard-link to file X, would u get 101 copies of file X within the backup or would it only store the file date once?

My idea is that backing up on the virtual level is perfectly possible from the hosting level. When you backup with a simple script you can get a list of all the virtual servers just by listing all the dirs in /home/vsd and then backup the dirs you want from every virtual server. Another advantage would be you can backup your skels with ease. I'm sorry I can't give you any concrete examples of programs/scripts, but I'm backing up Unix systems with homemade shell scripts and programs like 'dump' and 'tar'. It works for me, and it's easy to adapt to your needs.

I had read with interest the thread a while back concerning virtual server backups, and was wonder now that a little time has passed and there are (maybe?) some different ppl on the list, what sort of backup system you use? In essence, I really see only two main possibilities: backing up on the Hosting Server level, or backing up on the Virtual Server level. Which one do people tend to favour? On the one hand, backing up on the Hosting Server level is easiest, but what would you backup? I would thin the normal things on the Hosting Server (/etc, /var/log, /var/spool, mail, etc.), and then prolly either the entire /home directory, or just the part of the /home directory where the Virtual Servers are located. On the other hand, backing up on the Virtual Server level would enable you to specify only certain kei directories be backed up (/etc, /var/log, /var/spool/mail, /home, etc.), as opposed to the *entire* server.
