<DIV><FONT size=2 face=Arial>><FONT size=3 face="Times New Roman">the
attraction of a NAS is the built in features - web gui, sync to external
disk, notification of results via email etc.</FONT></FONT></DIV>
<DIV><FONT size=2 face=Arial>PVE have many of these features (sync to external
disk can run automatically with a script created by you and using crontab), but
i don't know why you want to have this feature?.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>> <FONT size=3 face="Times New Roman">With a PVE
server I'd have to script and test it all myself.</FONT></FONT></DIV>
<DIV><FONT size=2 face=Arial>For a side, with a NAS, ¿how can you test the
backups of VMs and without any kind of human interaction? ... and remember that
the backups are created in a vzdump format, so i am insecure that your NAS can
read this format kind of file.</FONT></DIV>
<DIV><FONT size=2 face=Arial> </DIV>
<DIV>Of other hand:<BR><FONT size=2 face=Arial>In my setup, the Backups are
programmed daily by the GUI PVE of the real Servers, obviously there is no human
interaction for do these tasks, and remember also that PVE send the mails
automatically making his reports.</FONT></FONT></DIV>
<DIV><FONT size=2 face=Arial>The idea of do a restore and starting the VM in the
Backup PC manually is only for do a check manually and be sure that there was no
some sort of strange problem.</FONT><SPAN id=result_box lang=en
class=short_text><SPAN></SPAN></SPAN></DIV><FONT size=2 face=Arial>
<DIV><BR>Making a comparison with the commercial leader product of Backups of
hypervisors (for VMware and Hyper-V):<BR>"Veeam Backup" do this tasks
automatically in chronological order:<BR>A) Make a backups automatically of the
VMs assigned<BR>B) Restore automatically the VMs in a isolated environment<BR>C)
Check automatically that the VMs can booting and starting<BR>D) Removes
automatically all traces of actions for declaration<BR>E) Send by email
automatically a complete report of his actions</DIV>
<DIV> </DIV>
<DIV>So, as the Backup system of PVE don't have the task of tests of backups
performed, i believe that it i can do manually when i want and with the VMs that
i want (only using the Backup PC obviously).<BR></DIV>
<DIV>Personally, i don't believe that if the email of PVE tell us that backup
are OK, in the practice occur otherwise, but as people say .... "one never
know until test it"</DIV>
<DIV> </DIV>
<DIV>>Why two bonded nics for the management connection?</DIV>
<DIV>Again, for four reasons:</DIV>
<DIV>1) It is only for caution, if a cable, or a NIC, or a physical port of the
Switch, or the same Switch break down, I will always have redundancy, and i will
be able to maintain always the network connection live, remember that my
Switches are in Stack mode (ie i have "HA" in all the Switches), so each NIC of
my PC Backup and my real Servers will be connected to different Switches that
also are in "HA".</DIV>
<DIV> </DIV>
<DIV>2) By other hand, for the Backup Servers and his connection to the LAN of
the company, Intel have NICs of 1 Gb/s cheap by amazon.com (model I-210), the
model is in this link:<BR><A
href="http://ark.intel.com/es/products/68668/Intel-Ethernet-Server-Adapter-I210-T1">http://ark.intel.com/es/products/68668/Intel-Ethernet-Server-Adapter-I210-T1</A></DIV>
<DIV> </DIV>
<DIV>Or more cheap with this model (Intel Gigabit CT Desktop Adapter), that also
support many kinds of network bondings:<BR><A
href="http://ark.intel.com/es/products/50395/Intel-Gigabit-CT-Desktop-Adapter">http://ark.intel.com/es/products/50395/Intel-Gigabit-CT-Desktop-Adapter</A></DIV>
<DIV> </DIV>
<DIV>And as i don't need performance for this kind of connection, any network
card that work well will be good, inclusive, speed of 100 Mb/s will
work well, these PCs will not be in the PVE cluster.</DIV>
<DIV> </DIV>
<DIV>3) The driver version of these Intel NICs are updated <SPAN id=result_box
lang=en class=short_text><SPAN class=hps>periodically </SPAN></SPAN>in the
kernel by PVE team (a preoccupation less for me)</DIV>
<DIV> </DIV>
<DIV>4) By other hand, for production enviroments, i have the good habit of
install all the network connections with some type of bonding mode, as
applicable, setup the most convenient (i always think that if i have "HA" in my
servers, why not have redundancy in his network connections?).</DIV></FONT>

class=gmail_quote>Hi Lindsay<BR><BR>Maybe you'd better have a PVE on a PC as
Backup Server instead of a NAS.<BR>Why i believe that it will be
better?<BR>For four reasons:<BR>1) You will can manually restore the backups
that were completed successfully on this same PC that also is running PVE
and test it for be sure that your files of backups are in perfect status for
his restauration.<BR>2) You will not need to use your real servers
doing such tests, and you will avoid performance degradation.<BR>3) If a
hardware component is decomposed, you only will need change the part that is
decomposed.<BR>4) If a PVE real server decomposes, and you don't have "HA"
enabled, your PC of backup will can help you starting the VMs that are
necessary in this same computer.<BR></BLOCKQUOTE>

<DIV>Thats an interesting thought Cesar, I'll look into that. Would be very
useful to have a test server.<BR><BR></DIV>
<DIV>OTOH, the attraction of a NAS is the built in features - web gui,
sync to external disk, notification of results via email etc. With a PVE
