==Introduction==

This will guide you through the process of installing and using the printers available within UMIACS.

==Printing Outside of UMIACS / Laptop Printing==

If you have a fully supported Windows laptop that is configured with DirectAccess you can access the printers just as you do from your desktop. If you are off the UMIACS network, you must first connect to the [[VPN]] on Windows. After you are connected, follow the instructions for adding a printer queue below. Please note that you must be on the VPN whenever your print.

==Pre-Installation Knowledge on Printing at UMIACS==

[[PrinterQueueNaming| Printer Queue Naming]]

==Installation of printer queue==

Please note that this applies to machines on any UMIACS network. This includes all proxy networks, the vast majority of machines in the labs, and machines connected to the UMIACS VPN but not the wireless network alone.

To add printer queues:

Go to start, click and type in “\\printers.pc.umiacs.umd.edu” in the search box.

'''You may be prompted with a box for authentication. Make sure to use your Windows Domain credentials, with 'pc\' prefixed to your username. (For example, if your username was 'johndoe' you would enter 'pc\johndoe' in the username box)

A list of printer queues will appear. Select your desired printer by double clicking on the queue. Once you have double clicked on the queue a box will immediately pop up to show you the status of the printer driver installation. Once that is complete you can start using the printer.

==Removing a printer queue==

To remove a printer queue, open the start menu and click on control panel. Next, click on "View devices and printers." To remove the queue, right click on the printer and select "remove device." If you wish to add the printer back, follow the instructions above.

==Duplex Printing==

Many printers in UMIACS support duplex (2 sided) printing. To make the duplex printing default, first make sure the appropriate printer queue is installed via the directions above. Afterwards, go to start, then “Devices and Printers.”
Once the printer has been installed proceed by right clicking on the queue then selecting “Printing preferences.”

After a few seconds the following menu will come up. Make sure you are on the “Printing Shortcuts” tab and select the “Eco-Print (Two-sided Printing)” option then click on okay. This modification will allow you to print 2-sided whenever you choose to use this printer.

Snapshots

Jdavis:

Snapshots are a implementation of [http://en.wikipedia.org/wiki/Copy-on-write copy-on-write] that allows for a file system to quickly take a point-in-time copy of the file system and provide access to the data through a .snapshot directory. Snapshots provide a fast, user-accessible way to recover data that has been accidentally deleted or corrupted within a recent time window -- rather than having to retrieve the data from comparatively slow tape backups. They also help to span the time gap between full backups.

We provide [[Snapshots]] on our [[Snapshots:NetApp | NetApp]], [[SnapshotsNexenta | Nexenta]] and [[Snapshots:FluidFS | FluidFS]] filers to certain file systems. If you are ever unsure if a particular volume has Snapshots enabled, please contact the [[HelpDesk | Help Desk]].

==Snapshot Policy==

Our core file systems in the department are on a 4 hour snapshot cycle. Snapshots are taken at,

{| style="color:green; background-color:#ffffcc;" cellpadding="5" cellspacing="0"
| 12am
| 4am
| 8am
| 12pm
| 4pm
| 8pm
|}

We retain up to 8 hourly snapshots, 2 daily snapshots and 1 weekly snapshot.

==Snapshot Restoring==

If you have deleted a file by mistake and you need to get it back, you can use the snapshots directory to recopy the file. This directory can typically be found in your home directory; it will be prepended by a ., so you will need to use the command "ls -a" to find it. It will be one of three:

* .snapshot for the [[Snapshots:NetApp | NetApp]] filers
* .snapshots for the [[Snapshots:FluidFS | FluidFS]] filer
* .zfs/snapshots for the [[SnapshotsNexenta | Nexenta]] / [[Snapshots:ZFS | ZFS]] filers

The inside of one of these will look something like:

For an example of file restoration, please see [[Snapshots:Example | this page]].
