Re: [Bacula-users] Sharkoon Quickport and Bacula

[Bruno F. <br...@io...>]

Hi Erik,

I'm using exactly this model.
I've been interested by the e-sata connexion, which can reduce drastly the load compare to the usb.

But with my Asus M2N-Pro the e-sata need to be plugged at boot to be usable.
You can unload it safetly after a backup. But I've not have success to put a new disk and have it
recognize at hot-swap (even stopping power on the dock ) I suppose the motherboard chip doesn't allow this
( under linux in my case ).

For the moment as I can live with the usb load, I'm working with it.

I've define a set of Label or UUID in fstab being mounted always at the same place and use a sub-directory
to place my bacula files.
I'm pretty sure, a set of udev rules would be better, but I'm not a guru udev's syntax :-)
I always manipulate by hands, as all external disk are encrypted so I need to give the key to mount them.

At last I recommend that you buy two pieces, you never know when one goes wrong (or power block).
