Page 15: Before Connecting The Bakstor
To set up the BakStor there are up to three connections that need to be connected. If an external tape device or tape library is to be connected the appropriate cables will have to be connected in addition. -
Page 16: Power
Connect the two 3-pin 100/240V AC power cable to positions J1 and J2. (Figure 2-3) Note that the power supplies are redundant; if one should fail the BakStor will still be able to operate. In the case of a power supply failure an alarm will bet set off. The alarm can be reset by pushing button L. -
Page 17: Ethernet 0
On a BakStor 1000 the powerbutton and reset button are located ABOVE the disk caddies. On a BakStor 2000 the powerbutton is located in the LOW and LEFT corner of the front panel. When viewing a BakStor unit from the rear correct orientation is ensured when:... -

Page 21: Configuration
The BakStor uses SATA disk drives. These are installed in the caddies provided. The BakStor 1U can use up to 4 disk drives and the BakStor 2U up to 12 disk drives. The BakStor comes with the disks preinstalled in the caddies. Should this not be the case the disks will need to be mounted in the caddies before they are inserted into the BakStor. -

Page 23: Shutting Down The Bakstor
Note that the current version of the BakStor is not able to create a RAID larger than 2TB. Depending on the capacity of the disks in the BakStor this may mean that not all the disks can be configured into a single RAID. In this case multiple RAIDs must be configured. -

Page 32: Activate Newly Build Raid
After a RAID has finished the building process it has to be activated before it can be put to use and before slices can be created on top of the RAID. Choose RAID Menu ? Add array to BakStor in order to activate the new RAID. Choose the correct RAID to activate and click the ACCEPT button. -
Page 33: Repairing A Raid
4.3.1 Repairing a RAID First the failed disk drive needs to be removed from the BakStor. To configure the BakStor to expect a faulty disk drive to be removed, choose RAID menu ? Repair a RAID ? Remove faulty drive All currently failed disk drives will appear in the Select slot pull-down menu. - Page 34 The replacement disk drive can then be configured into the RAID.

Page 37: Snapshots
As the original disk slice is modified the snapshot can be used to "go back in time" to the time the snapshot was taken. A snapshot can be exported and mounted on an iSCSI initiator computer just like a regular disk slice. The snapshots on a BakStor are both readable and writeable. -

Page 40: Creating An Aiir Process
Tandberg Data 4.5 Creating an AiiR Process In addition to making a single snapshot (either instant or scheduled) the BakStor has an option for scheduling multiple snapshots to be scheduled. The BakStor’s ‘AiiR’ module contains a snapshot scheduler that can configure and run up to 100 snapshots. -
Page 41: Starting An Aiir Process
Slice name. The name of the slice for which the AiiR process has been defined. Click the ACCEPT button. Note: While an AiiR daemon is running the BakStor will monitor for free disk space available for the daemon. If more than 75% of the space allocated for the AiiR snapshots is used, the BakStor will automatically attempt to increase the snapshot space by 1GB. -
Page 42: Adding Secure Authentication (Chaps)
4.6 Adding Secure Authentication (CHAPs) The BakStor 1U and 2U products both support secure authentication (CHAPs). This allows to set password protection on both the BakStor unit and also on individual slices and virtual tapes. 4.6.1 Setting a Password for the BakStor Setting a username and a password for the entire BakStor will prevent iSCSI initiators that do not have the username and password from connecting to the BakStor. -
Page 43: Setting A Password For An Individual Slice
Tandberg Data 4.6.2 Setting a Password for an Individual Slice Instead of or in addition to restricting access to the entire BakStor access control can be configured for each defined slice. This allows for even greater control over what iSCSI initiators can access a given resource on the BakStor. - Page 44 Tandberg Data This Page Intentionally Left Blank BakStor Installation and Administration Manual...
-
Page 45: Connecting And Using External Units
The BakStor Expansion Unit allows for more storage space to easily be added to the BakStor solution. The BakStor Expansion Unit is a 2U unit with 12 internal disk drives that compliments the BakStor 2000. In such a configuration the BakStor 2000 will be referred to as a BakStor Master Unit. -
Page 46: Detecting And Configuring The Bakstor Expansion Unit
Once the BakStor Expansion Units are discovered they can be configured with RAID sets. Choose BakStor EX ? Config / View BakStor EX Then select the BakStor Expansion Unit to configure and click on the link in order to connect to the specified BakStor Expansion Unit. -
Page 47: Powering Down A Bakstor Expansion Unit
Note: Once slices have been defined on the RAID sets located on the BakStor Expansion Unit the unit can no longer be detached from the BakStor Master Unit. If detachment is required the slices must be deleted. All data located on the slices will be lost. - Page 48 Unit. Click ACCEPT. 3. Choose Configuration ? Network configuration ? Create a team Select the two ports that are to form the AFT link to the BakStor Expansion Unit. Then select AFT as the mode. Click ACCEPT and ignore any error messages.

Page 50: Using An External Tape Device
This will provide a list of all tape devices recognized by the BakStor. If a tape library is connected a tape map of the library will be displayed as well. If the tape device is not recognized select yes and click the accept button to force the BakStor to rescan the SCSI bus. -
Page 51: Selecting Encryption Method For Moving Data To Physical Tape
Tandberg Data that can only be restored on a BakStor unit. As with diskslices the data can be encrypted before it is copied to the physical tape. Application mode creates a physical tape in a format of the application that was used to write to the Virtual Tape. -
Page 52: Checking Contents Of A Physical Tape
This prevents accidentally overwriting a tape containing data that should be saved. Choose Backup Menu ? Restore menu ? Check tape contents If the tape has previously been used to back up a slice from the BakStor the name of the slice will be displayed. - Page 53 To run the backup immediately, choose Backup Menu ? Run a defined backup now. Then choose the name of the slice to be backed up. Click the ACCEPT button to start the backup. Figure 5-2 Starting a defined backup BakStor Installation and Administration Manual...

Page 54: Scheduling A Backup
No check will be done to verify if the tape contains data and any data already on the tape will be overwritten. The backup schedule has now been created with start at the entered time/day/month. Figure 5-3 Configuring a scheduled backup BakStor Installation and Administration Manual... -
Page 55: Restoring From A Physical Tape
If the slice does exist the BakStor can overwrite the current data on the slice with the data stored on the physical tape. If the slice is no longer available on the BakStor or there is a need to restore the data on a different BakStor unit it is possible to recreate the entire slice from physical tape. -
