I also took a look at the tsmafs module and had a couple technical
questions about how it works.
1. What happens when you rename a directory (either a volume
name or within a volume)? Does the entire directory need to get
backed up again?
The entire directory/volume will be backed up again. But you can
change where the volume is mounted.
Hm, the volume id is saved and used when checking if volume needs
backup, so it will probably be simple to check if it needs renaming.
Just haven't thought of it :-)
2. While the use of hard links is limited in AFS, will tsmafs
preserve those links on restore?
No. We currently use the normal TSM commands to restore files and
those knows nothing about AFS, so I don't think so. I have not checked
if we store metadata to be able to do that if we write a dedicated
client.
Everything else is stored except for the hard link info (which would be
easy to add). Hm, I think I just didn't think about that when I wrote
tsmafs :-)
If you use tarestore you should get everything except hard links on restore.
