Below is a new version of the backup script that I posted to USENET on
5 July 2005 (initial version) and 9 Sept 2006 (revised version). This
new version can also be found at:
http://www.derkits.com/apps/serverbackup.txt
(be sure to change the file attribute to .cmd before using it)
The version below may be affected by line wrapping. So, it is
probably best to download the script from the above URI.

The main improvements are:
- Inserted code after the backup operations and before the robocopy
operation to parse the ntbackup logs for certain error messages that
will indicate a problem even if ntbackup returns a "success"
errorlevel.
- Under Exchange backup section, corrected position of line "set
saveerrorlevel=%errorlevel%".

This is still a caveat:
- Robocopy, when run in a batch script, can have problems with very
large backup (.bkf) files. I have noticed this with individual .bkf
files that are around/over 110GB in size, and it is more likely to
occur on servers that have the /3GB switch enabled in boot.ini. In
some cases, rebooting the server will resolve the problem, at least
termporarily. One workaround is to copy the file manually, using
robocopy or another method. But, if you are encountering this error
often, then your infrastructure may have outgrown the capabilities of
this script. For additional information on this robocopy "bug",
search
the web for: robocopy insufficient resources. See also:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q259837


Some text from my earlier post is still relevant, so I'll repeat it
here.

"Below is a batch-based script that I have developed for a few
clients
in setting them up with disk-based backup (using USB2 and/or FireWire
external hard drives, such as those available from AcomData and
others). I'm posting it here in case anyone has a use for it.

This material is supplied without any warranty or support. You
should
periodically test the quality of your backups no matter what backup
software you use, including running test restores on test hardware.
Although this backup script should be usable "out-of-the-box", it is
best if the sysadmin reviews it and makes an effort to understand it,
before actually using it. This is freely-available (no copyright)
and
may be copied/customized/used as desired.

Reasons to consider a disk-based backup approach:
- Disk backup is usually considerably less expensive than tape
backup,
once all of the hardware and software are factored in. This is
certainly true at larger data sizes, which is sometimes the
case for file servers and/or email servers.
- Disk backup is usually faster than tape backup, and easier to
restore
from.
- Disk drives are usually more portable than tape drives, and they
have
strong OS support (with the drivers preloaded in most cases).
- This backup script is free, and it leverages the capabilities of
ntbackup, which comes with Windows for no additional cost.
- Disk backup can be easily scheduled using Scheduled Tasks.
- Off-site capabilities are easily supported, by having one external
drive always attached to hold the backups, and then another drive (or
set of drives) that mirror the content of the always-attached drive
and
that rotate a few times per week - e.g. at any given moment, one
rotated drive is attached, one is in transit, and one is safely
off-site). See the script for additional details about this
mechanism.

Granted, this backup script is a batch file, but for relatively
simple
purposes a batch is okay (using cmd, not bat, of course). If I were
doing this formally, I'd probably write it in vbscript, but batch is
somewhat more accessible to the Windows community.

Feel free to email me if you find any bugs or have any comments.

Enjoy,

@echo off
echo Version 2.50 (25Aug07) - David Derkits
(dderkits@alumni.caltech.edu)
echo Runs a backup to two external hard drives and logs progress and
errors
echo into an email.
echo This script can be executed manually but, in practice, is usually
run
echo automatically using Scheduled Tasks.
echo This script must be run locally on the server that is to be
backed-up.
echo.
echo Command syntax:
echo.
echo serverbackup.cmd weeknum baktype
echo.
echo where weeknum is: 1, 2, or 3 (assuming a three-week rotation;
this
echo script supports, without modification, rotations of longer or
echo shorter duration). Generally, weeknum is: 1, 2, 3, ..., n
echo Note that weeknum can generally be thought of as a "rotation
number";
echo it does not necessarily have to align on a weekly repetition.
echo.
echo where baktype is: normal or diff
echo.
echo example:
echo backupscript 1 diff
echo.
echo Changelog:
echo 8/25/07: Created version 2.50. Inserted code after the backup
echo operations and before the robocopy operation to parse the
ntbackup
echo logs for certain error messages that will indicate a problem even
echo if ntbackup returns a "success" errorlevel. Under Exchange
backup
echo section, corrected position of line "set saveerrorlevel=
%errorlevel%".

rem THIS FILE IS MADE AVAILABLE WITHOUT ANY WARRANTY OR SUPPORT. You

rem software you use, including running test restores on test

rem Although this backup script should be usable "out-of-the-box", it

and
rem may be copied/customized/used as desired.

rem -----
rem BEFORE USING THIS SCRIPT FOR THE FIRST TIME

rem 1) Edit the Script Customizations (next section, below).

rem 2) Attach two external hard drives such that they are assigned
drive
rem letters by the Windows OS. Format these drives using NTFS.
rem 1) Designate one drive as the Fixed Drive, and create a file at
the
rem root of the drive that has a filename matching that shown in
the
rem Script Customizations section below.
rem 2) Designate the second drive as the Rotated Drive, and create
a file
rem at the root of the drive that has a filename matching that
shown
rem in the Script customizations section below.
rem 3) In most cases, there will be more than one Rotated Drive, so
that
rem one drive is connected, one is in transit, and one is off-
site.
rem Follow the above step for each such Rotated Drive.

rem 2) If the script will be used to back-up Exchange data, then
rem create the exchange.bks file locally as follows:
rem 1) Open Windows Backup (Start button -> All Programs ->
Accessories ->
rem System Tools -> Backup.
rem 2) If Backup launches in "Backup or Restore Wizard" mode, then
uncheck
rem "Always start in wizard mode", click Next, click Next, click
Cancel,
rem and relaunch Backup.
rem 3) In the "Backup Utility" window, go to the "Backup" tab.
Find the
rem "Microsoft Exchange Server" section and expand it you see
the
rem "Microsoft Information Store" entry. Checkmark the checkbox
rem next to this entry.
rem 4) Go to menu bar Job -> Save Selections As..., and save the
file as:
rem c:\active\scripts\serverbackup\exchange.bks
rem (or whatever file/path that is entered in the Script
Customizations
rem section below)
rem 5) Close Windows Backup. The file is now created.
rem NOTE: The exchange.bks file will have to be manually recreated
whenever
rem an Exchange Storage Group is added or deleted (so that the
rem exchange.bks file is aware of the change).

rem 3) Create the Alert Group (ga.*) in the Active Directory
rem (see the "emailaddress" variable below for the name format).
rem Example: ga.servername.backup-notify
rem (This step can be skipped if the email address to which backup
rem reports will be sent already exists.)

rem 4) Modify the Registry so that only one backup log (rather than
rem 10 logs, rotated) is used. To do this, load the registry file
rem ntbackup-onlyonelog.reg (which is usually located in the same
folder as
rem serverbackup.cmd) under the user account that ntbackup will
rem impersonate when conducting its backups.
rem For reference, this is the content of the .reg file (note: two
lines):
rem [HKEY_CURRENT_USER\Software\Microsoft\Ntbackup\Log Files]
rem "Log File Count"=dword:00000001

rem 5) Set up the Scheduled Tasks if Scheduled Tasks are to be used.
rem For each week (or "rotation"), there are normally two Scheduled
Tasks:
rem (assuming a three-week rotation and a 12am start time; note
that a
rem three-week rotation would require a total of six Scheduled
Tasks)
rem "Backup Week 1 Normal"
rem Run: c:\active\scripts\serverbackup\serverbackup.cmd 1
normal
rem Schedule: Weekly, every 3 weeks, at 12am on Monday
rem "Backup Week 1 Diff"
rem Run: c:\active\scripts\serverbackup\serverbackup.cmd 1
diff
rem Schedule: Weekly, every 3 weeks, at 12am on Tues, Weds,
Thurs,
rem Fri, and Sat
rem For both:
rem Run as: DOMAINNAMEHERE\Administrator
rem Enabled
rem Rest of the settings = use the defaults
rem The backup script can handle any Scheduled Task configuration,
so the
rem above is just one example of many possible tasks.

rem SCRIPT CUSTOMIZATIONS

rem 1) Specify the server to be backed-up
rem
set srvname=servername

rem 2) Specify the names of the files to be placed at the root of the
external
rem backup drives to indicate their eligibility as backup drives:
rem (this is crucial in preventing accidential erasure of data)
rem
set fixedfilename=autobackup-fixed-ok.txt
rem
set rotatedfilename=autobackup-rotated-ok.txt

rem 3a) Specify whether the server needs an Exchange backup:
rem use "true" or "false" (w/o quotes)
rem
set bakexchange=false
rem
rem 3b) If an Exchange backup is specified, on the server in question,
ensure
rem that the exchange.bks file exists, and specify its path:
rem
set exchangebksfile=c:\active\scripts\serverbackup\exchange.bks

rem 4a) Specify whether the server needs to backup a file on another
rem server:
rem use "true" or "false" (w/o quotes)
rem
set bakother=false
rem
rem 4b) If this is the case, then specify the location of the file,
using its
rem full file name and its UNC path:
rem
set otherfile=\\otherservername\c$\backup\otherserver-drivec-
sysstate.bkf
rem
rem 4c) Specify a friendly name for this backup:
rem
set bakothername=otherserver-drivec-sysstate
rem
rem Note: A backup of a file on another server will only be done
during
rem a backup of type normal (i.e. baktype=normal). Be sure that the
user
rem account under which serverbackup.cmd runs has the right to access
rem the other location.

rem 5) Specify the email address that will be used in the From: and
To:
rem fields of the emailed backup report:
rem Example: ga.%srvname%.backup-notify@company.com
rem
set emailaddress=ga.%srvname%.backup-notify@company.com

rem 6) Specify the Exchange email pickup folder. The user account
under
rem which serverbackup.cmd runs must have write access to this
location.
rem For authentication purposes, this location should be in the
same
rem Windows domain as the server on which the backup script is
running.
rem
set exchpickup=\\mailservername\c$\Program Files\Exchsrvr\Mailroot\vsi
1\PickUp

rem -----

rem Note: Carets are used to wrap lines that extend beyond 80
characters.
rem Note: The line "cmd /c exit /b 5" is used to set the errorlevel to
a
rem non-zero value so that we know that the next command
executed
rem at least to the point that a new errorlevel was set.

At around 700 lines, this is probably the largest batch file I have ever
seen. I seriously wonder how maintainable and modifiable it is by
anyone other than its author, and I suspect that even its author would
have a serious problem if he attempted to modify it after not working
with it for a whole year. I believe it would gain enormously if it was
structured instead of having 700 lines one after the other. This could
be done like so:

call :SetVar
call :DelLog
call :WriteHeader
call :CheckLocal
goto :eof

-----------------------------
Set various env. variables
-----------------------------
:SetVar
set baklog=%temp%\backuplog.log
set robolog=%temp%\robocopylog.log
set emailtop=%temp%\emailtop.txt
set ntbackuplog=%userprofile%\Local Settings\Application
Data\Microsoft\Windows NT\NTBackup\data\backup01.log
set ntbackupall=%temp%\ntbackupall.log
goto :eof

-----------------------------
Delete old log files
-----------------------------
:DelLog
del "%baklog%"
del "%ntbackuplog%"
del "%robolog%"
del "%emailtop%"
del "%ntbackupall%"
goto eof

A big advantage of such structured code is that it becomes very
easy to test each module separately, by simply modifying the
initial list of "call" statements.
