Given:
Guess, how long will it take to back up 1.7TB of mostly big files to a directly connected eSATA disk using standard GUI commands?

I thought that nothing could be easier on Solaris than to mount a directory from a QNAP NAS (running Linux). Ha! Nope… Here’s some gotchas.
QNAP firmware v2.x does not support NFSv3 or NFSv4, so you have to explicitly use “-o vers=2”. As a result, you cannot use files bigger than 2GB (no problems with SMB).
QNAP firmware v3.2.x supports NFSv3 (use “-o vers=3”) but does not support NFSv4. Big files are back, but to get the AUTH_SYS authentication back too, add “sec=sys” to the options string (considering that users on the NAS box have the same UID’s as on Solaris).
xeon# mount -F nfs nas:/photo /mnt nfs mount: nas:/photo: No such file or directoryxeon# mount -F nfs -o vers=3,sec=sys nas:/photo /mnt xeon#
Or use the automounter:
xeon# more /etc/auto_master . . . /nas auto_nas -nobrowsexeon# more /etc/auto_nas * -vers=3,sec=sys nas:/& xeon# svcadm restart autofs xeon# xeon# cd /nas/video xeon#
The directories must be exported as “No Limit” access rights (UID’s and standard file access modes will be used).
