I can run a zip command directly from the gluster node, or I need to mount it on the backup server than run the command? Is there any other good solution to store a backup?<br></div></div></blockquote><div><br></div><div>I don't see it'd make much difference. If it's lots of small files though, there could be a performance hit. If it did become an issue, it might be more efficient exporting snapshots (assuming your bricks are backed by LVM. ZFS would make it even easier).<br><br> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div></div><div>3) Can I share WebApps folder between Tomcat servers? Is there any known issue? (for example putting a .war into the WebApps folder, I think I'll generate some errors due to tomcat war deploying? Anyone have experiences with tomcat and glusterfs shared folders?)</div><div><br></div><div>4) Can I use a load balancer software to mount GlusterFS volumes?
