Disaster Recovery Do's & Don'ts Do:
Update DR tapes/floppies whenever there are system changes
Test DR procedures Make sure DR tapes/floppies are safely
stored• Store tapes and DR bootkits together• Tapes and bootkits are properly labeled
Don't use DR software for: Server Migration As a chance to do a hardware upgrade To clone servers

How Disaster Recovery Option Works on NT/2000 DR information collected during full backups only
Data stored in ARCserve$/DR/<Machine Name> DR recovery information can be created three
ways: Generic Bootdisks
• Windows NT only Machine Specific Bootdisks
• Will auto-partition machine, restore settings Bootable Tape
• OBDR support CD Based DR
• Coming Soon!

Disaster Recovery Option Limitations DR on Windows 2000 does not currently support
Remote DR for 2000 machines (coming soon) Tape based OBDR support (coming soon) DR over SANs (coming soon) Generic DR bootdisks
• System State makes machine specific bootkits a requirement
EISA Partitions Must be restored before DR begins
RAID Arrays Must be setup before DR begins

Performing Your Backups Must be full backups
Icon for the machine should be full green Backups of remote machines MUST be made
through the NT/2000 client agent Check activity log for warnings/errors related to
DR process A few open files should not affect the DR process Errors to look for are:
• Run Windisk to generate DR information• Failed to create DR information errors

Creating Your Bootkit
Bootkit wizard Wizard shows which
bootkits are available (OS dependent)
Bootkit requirements 4 disks for Generic NT 5 disks for Specific
NT/2000 1 tape for OBDR (NT only)
If using disks, Disaster Recovery uses: Modified versions of
Windows NT/2000 setup disks
ARCserve specific recovery disks

Steps for Creating Your Bootkit1. Select your Bootkit type2. Select your ARCserve Server3. If using floppies:
Select Generic orMachine Specific
For Specific disks,select the machineto create disks for
4. Start the Bootkitcreation.

What’s on the Boot Disk? First 3 are modified NT setup disks 4th disk contains the ARCserve recovery
software 5th disk contains machine specific
information Network drivers System and Security registry hives
Partition information (partinfo.ppp) Found on the 3rd bootdisk Should be removed when:
• Using RAID arrays• Using EISA partitions• Trying to disable the auto-partitioning

Troubleshooting Bootkit Creation If machines do not appear as available for
DR in the Bootkit Wizard: Check that full backup was performed Check for errors in the activity log
If the Bootkit Wizard is unable to copy files to disk: Make sure disks are formatted Damaged disks may not have full capacity Use chkdsk to check for disk capacity
If hardware is changed, or reconfigured Run a new full backup Update the bootkit!

Performing Disaster Recovery What do you need to perform a DR?
Tape with full machine backup ARCserve DR Bootdisks (if using disk
based method) Windows NT or 2000 CD Hardware specific drivers (with NT 4.0)
1. For the most part, disk-based DR is following onscreen prompts
2. NT 4.0 – The first step. Do I choose custom or express setup? Choose custom if
• Changing the hard drive • Need to load hardware specific drivers

Performing Disaster Recovery (con’t)2. Once the NT/2000 setup disks are finished, the
DR wizard starts: DR wizard allows you to select the tape drive
where the backup session is located. Select the partition to recover Modify partition
information3. Selecting the tape device
to use for the DR Supports remote on NT Local on NT and 2000

The DR Wizard allows:• Creation of partitions• Modification of partition information/size• Assigning of sessions to different partitions

Special Considerations
Language/OS Support Check release notes for supported NT/2000 versions
Using MTF tapes ARCserve can not determine if sessions are full or partial DR does not support all automated features
Windows 2000 systems with single instance store: Run AsSISChk.exe from ARCserve directory after booting up
• Completes restoration of SIS specific information Machines with EISA partitions:
ARCserve does not recover EISA information Recreate EISA/other partitions before starting DR process
• Using DR wizard to repartition may destroy EISA information

What To Look Out For
Custom Setup (NT 4.0) Make sure the latest drivers are on hand for equipment
If the hard drive was switched Drives must be attached to the machine like the previous
• Replace SCSI drives with SCSI, IDE with IDE• Attach to the original controller card
Drives must be the same size or larger than original Switching other hardware
Hardware should be replaced by the same model After DR is over, NT/2000 will be looking for the original
hardware• The restored registry thinks it’s on the original machine!• Blue screens will occur as the machine boots up, looking for
the original SCSI controller, etc.

The Last Resort: What to do if you have an issue
1) Reinstall the OS to x:\tempNT 2) Reapply service packs3) Reinstall ARCserve or the NT/2000 Client
Agent4) Reapply ARCserve or Client Agent patches5) Restore the volume6) Alter the boot.ini to point to the x:\winnt
directoryCheck support document 16046 for more
