Hello,
I am trying to save some FS on tape using snapshots and I get an error :
tar: ./devices/pseudo/sysmsg@0\:sysmsg: Cannot savedir: No such device or address
after more than 20 minutes and #75000 files copied.
The process used :
1) fssnap the FS
2) mount de the snapshot pseudo device
3) tar from the mountpoint to a tape
Any help much appreciated !
Regards

Its best not to touch /dev and /devices with tar since it really makes no sense trying to back those up. The whole structure is managed by the device manager, so it wouldn't make sense trying to restore this to another machine.
If you're looking to make snapshots of your filesystem look into the 'fssnap(1M)' command, that can be used to create snapshots which you can then mount and from there create a backup. You might also want to look into commands like ufsdump(1M) for making backups instead of tar.
