Now that we have 3 way NDMP, we can exchange data between any and all arrays that support it, over the network, sending encapsulated block data directly from one array, to another. Then more features have been added, such as 3-way NDMP, which allowed the data stream to go back to the network, encapsulated, to another server, essentially putting the backup traffic back on Ethernet, for special cases, or stubborn shops that just didn't believe in Fiber Channel This is in essence how basic 2-way NDMP works as far as NDMP backups go. Hundreds of filers, with petabytes of data, can now be all backed up simultaneously and other network traffic is not affected. Let all willing ( NDMP enabled ) NAS devices do their own backups, directly to tape, real or virtual, over Fiber Channel Fabric ( avoiding the Ethernet network ) and only transmit the file index back to the backup server, off-loading all data traffic from the network. ( now known as EMC Networker ), in partnership with a little known NAS vendor - NetApp, recognized the problem and came up with an interesting solution. Legato, the developer of one of most popular backup programs The commonly used client > Ethernet > server > tape library - backup model worked great until the proliferation of NAS ( Network Attached Storage ) devices took place.Įver growing NAS devices, over-saturated with data that constantly needed to be extracted over the network to be backed up, over and over again, became a major threat - holding data hostage - too much data, too little time to copy it over the network and write to tape. The best way to migrate network shares between NetApp and Isilon is to utilize the NDMP protocol. Import the root zfs pool by running " zpool import -f rpool" command.Īfter that, you should different boot environments ( root zfs snapshots )Īnd mount the version that you last booted.Īfter the environment successfully mounts, proceed to cleaning up the /var/ld directory, or fixing the contents of /var/ld/ld.config, if you actually have custom library paths defined.Īfter that, a simple reboot will bring up the system it its original state, with the default library search paths. The recovery process on Solaris 11 is very straightforward.īoot from the Solaris 11 CD and enter the shell ( Option 3 in the CD loader menu ) When faced with a crash, resulting from the use of crle command, not all is lost. To avoid this, all system libraries need to be discovered and prepended before the new library search path.Īn even safer way to do this, is to use the "crle -u" option, which will gather all the default system library paths, append the new one provided and save them all to /var/ld/ld.config file. In a its "most impatient" form "crle -l" of simply providing the path to the new library, if executed as root, renders the system unusable and results in an immediate crash. The need for init script LD_LIBRARY_PATH setting, etc. On the Isilon side, to be able to set the security info, you may need to apply generic aclsĬhmod -R a user mydomain\\myuser allow generic_all /ifs/share1ĬRLE utility on Solaris is used to create and manipulate the runtime linking configuration file - also known as the library search path ( Solaris alternative to LD_LIBRARY_PATH variable )Ĭrle -l option is used to add a new library search path, which will persist upon reboot, avoiding PURGE - synchronize deletes from the source to the target COPY:ALL - preserve metadata ( file attributes, ownership, ACLs, etc ) DCOPY:DT - preserve file and directory time stamps MIR - mirror the directory structure on the target Robocopy /MIR /DCOPY:DT /COPYALL /PURGE Z:\share1\' ' \\isilon.my.\share1\' The syntax isn't overly intuitive and uses Microsoft style options. Robocopy can even work with NFS shares, if the Windows system you're working with has the NFS functionality enabled. Windows, Hitachi/BluArc, NetApp, various EMC VNX, Samba, Oracle ZFS, etc.are all at SMB 2.1 or higher as of June, 2104. All standard CIFS implementations are known to work, as of SMB version 1.0 and starting with version 2.1, robocopy can employ multiple threads for data transfers. It can be used with any CIFS providers for local-dir > network share, or network-share > network-share migrations. It is used for batch copying large volumes of data between local directories, or network shares. Robocopy is a command line tool, built intoWindows operating system.
