ba ckup, Avama r will temporarily re-inflate the file ba ck to its full size be fore ba cking up the
file to the Avama r server. After the backup operat ion, the file will still be d eduplica ted o n

All Avama r ba ckup opera tions with th e Windows VSS plug-in use the Microso ft Softwa re
Shadow Copy provider, also known as the Microsoft system provider. Hardware providers
a re not supported.
Windows Server 2008 and 2012 Core Insta llationsIf you deploy Windows Server 2008 or 2012 using the Core Insta llation fea ture, you do no t
ha ve access to the trad itional full graphica l user interface (GUI). Therefore, you must
insta ll and mainta in the Avama r Client for Windows so ftwa re entirely from a DOS prompt
using the msiexec utility. “ Windows Server 2008 and 2012 Core Insta lla tion and
maintenance” on page 28 provides additional information.
Disabling NTFS Last Access Time inh ibits ba cking up changed ACLs
If the NTFS Last Access Time fea ture is d isa bled on a Windows ba ckup client, the Avamar
Client for Windows so ftwa re is no t a ble to dete ct a ny further Windows ACL changes . This
means tha t the ACL se tting s tored d uring the origina l file ba ckup is the ACL se tting tha t is
applied on all future restores.
The NTFS Last Access Time fea ture is enabled by d efa ult, but is s ometimes disa bled for
performance purposes .
To re-es ta blish proper Avamar Client for Windows ACL ba ckup beha vior:
1. Enable the NTFS Last Access Time feature using one of the following methods :
• Specify a value of 0 in the following registry entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\
NtfsDisableLastAccessUpdate.
A value of 0 ena bles Last Access Time, while a value of 1 disa bles Last Access
Time.
• On Windows 7, Windows S torage Se rver 2008, Windows Server 2008 R2, Windows
Sto rage S erver 2008 R2, Windows Server 2008,Windows XP, Server 2003, a nd
Vista platforms, type the following command from a command prompt:
fsutil behavior set disablelastaccess 0
2. Delete the following local Avamar Client for Windows ca che files:
• C:\Program Files\avs\var\f_cache.dat
• C:\Program Files\avs\var\p_cache.dat
This ca uses the re-creation o f the files the next time tha t a ba ckup occurs for the
client.
NTFS soft links a re skipped by default in Window s VSS ba ckups
Avamar Windows File System b ackups us ing the Avamar Windows VSS client w ill skip
NTFS so ftlinks (also known a s symbolic links or symlinks). In a ddition, if a n Exchange,
Sha rePoint, or Windows S erver is configured to sa ve either data ba se files or log files to a
so ftlink pa th, b ackup will fa il. EMC plans to fix this in a future releas e.
Avamar does make an exception, as noted in Ba cking up a s ingle directory or file on a
mount point, directory junction, or d irectory symbolic link .

Backing up a single d irectory or file on a mount point, directory junction,
or directory softlink
Avamar supports b ackup and restore of individual files and d irectories on a :
◆ Mount point
◆ Directory junction
◆ Directory symlink
◆ File symlink (ha rdlink or so ftlink)
This is only supported for local file systems ; it does not a pply to network drives. It is
recommended that you recreate the mount point, directory junction, or directory softlink
before performing the res tore. The conte nt will be res tored to th e original locat ion as long
as the mount point, directory junction, or directory so ftlink exists. If it does no t exist ,
Avamar crea tes a directory path matching the ba ckup path a nd the content is restored to a
loca l directory with the link name.
Use Avama r Client for Window s to ba ck up SQL Server Resource da ta ba seThe SQL Server Resource da taba se is a read-only data ba se tha t conta ins a ll the system

up the Resource data ba se, mssq lsystemresource.mdf, or its log file,
mssq lsystemresource.ldf, because SQL Server cannot ba ck up the Resource da taba se. To
ba ck up Resource da ta ba se files , use the Avama r Client for Windows .

Add a vta r.exe to a nti-virus a pplica tion sa fe list s
Some anti-virus (AV) applica tions may reduce the pe rformance of Avama r ba ckup
opera tions. In most ca ses with AV applications , when a progra m opens a file, the AV
application scans the file to check for viruses. If the AV applica tion sca ns ea ch file as it is
ba cked up, then the disk and ba ckup program performance will be s low.
To reduce ba ckup times and prevent the AV application from performing a sca n of ea ch file
as Avama r backs it up, a dd the a vtar.exe file to the exclusion or sa fe list for the AV
application. The settings and user interfa ces to do this depend on the AV application. For
example, McAfee refers to thes e exceptions a s low-risk processes.

Backup launch methods a nd types 35
Backup
Application restores a fter disa ster recovery
The Windows VSS plug-in disa ste r recovery ba ckup includes applica tion b inaries loca ted
on critical volumes, if those files a re not protec ted b y an a pplication plug-in. This typica lly
applies to applica tions tha t use a Windows service. For exa mple, Exchange executa ble
files a re included , but the d a taba se a nd log files a re excluded from the disas ter recovery
ba ckup. During disas ter recovery, these applications a re restored to a functional sta te, butit may be neces sa ry to restore a pplica tion da ta using the application plug-in. If an
application wa s insta lled on a non-critical volume and the volume was des troyed, then
you must either res tore the non-critica l volume from a Windows File System plug-in
ba ckup or reinsta ll the a pplication.
Backup launch methods and types
After you a ctiva te a client, there a re severa l ways to perform ba ckups, a nd s evera l types of
da ta you can back up. Avamar clients a re typically ba cked up a utomatically by way of
regularly scheduled backups initia ted b y the Avamar server. Data can a lso be restored b y
the sys tem ad ministra tor using Avama r Administrator. However, “o n-demand ” b ackup and
restore opera tions ca n a lso b e initiated directly from the Avama r Administrator UI.
The Avamar Client for Windows does not s upport backup and recovery of the Windows XP
Mode component in Windows 7.
Backup retention
The retention settings for a ba ckup control how long the ba ckup da ta is kept on the
Avama r server. Poss ible retent ion settings a re:◆ No end date (keep the backup indefinitely)
◆ Keep the ba ckup for a s pecific number of da ys, we eks, months, or years
◆ Keep the ba ckup until a specific ca lendar da te
To support certa in ad vanced fea tures, Avama r Administrator automa tica lly ass igns one or
more retent ion types to every ba ckup. For example, the first ba ckup created on the Avama r
system is ta gged a s d a ily, weekly, monthly, and yearly. You can a lso manua lly change the
retention types as signed to a backup.
Va lida ting a ba ckup
You can a lso verify that files ca n be restored from an existing ba ckup. This va lidat ioninitiates a “ virtua l” restore of a ll files in the ba ckup but does not a ctually restore any files
to the client filesystem. The EMC Avamar 6.1 Adminis tration Guide provides complete
instructions for monitoring a backup, restore, or validation.

Backup
Interna tional characters
Avamar generally supports the use of s pecific supported internat ional cha racters in
directory, folder, and filenames. However, proper display of international language
characters is contingent on the client computer loca le and installed system fonts being
compatible with the original language. If you a ttempt to browse b a ckups tha t were crea ted
with interna tional characters a nd you do not ha ve a compa tible font installed on yoursystem, a ny characters that cannot be resolved by the system will be displayed as
recta ngles. This is a norma l limitation of that pa rticula r situa tion and do es no t a ffect the
ability to restore thes e directories, folders, o r files. The EMC Avamar Relea se Notes
provide additional international language support informa tion.
Backup la unch methods
Avama r provides severa l ways to initiate a Windows Server backup or res tore:
◆On-dema nd using Avamar Administra tor
This metho d ena bles you to perform backups of a Windows server between regula rlyscheduled b a ckups d irectly from Avama r Administrator. It is a good practice to perform
an on-demand ba ckup before syste m upgrades , installations, or any major changes to
the s erver. You may a lso wa nt to perform an on-demand b ackup immediately after you
insta ll and register the Avama r Client for Windows . “ On-demand ba ckup” on page 39
provides steps to perform this procedure.
◆ Scheduled using Avama r Administrator
This metho d ena bles you to schedule regular ba ckups of a Windows se rver directly
from Avamar Adminis trator. “ Scheduled backups” on page 56 provides steps to
perform this procedure.
You can a lso a utomate ba ckups by implementing a group policy to perform regularlyscheduled ba ckups for an entire group of clients. The EMC Avamar Administra tion
Guide provides additional information a bout groups a nd group policies.
◆ On-dema nd us ing the Avama r client interface
Typically, this method is used by a n end-user who wa nts to ba ck up or restore da ta on
an individua l machine. This method s upplements but does not repla ce regularly
scheduled ba ckups initia ted by the Avama r server. The EMC Avamar Backup Clients
User Guide provides more informa tion about pe rforming backup and restore of
Avama r Windows Clients using on-dema nd ba ckup.

Backup
Da ta types a nd files a vailable for ba ckup and restore
Backup and recovery for a Windows s erver is more tha n just ba cking up data ba ses a nd
da ta files tha t reside on tha t server. A Windows s erver can s erve a wide variety of roles in a
network, so it is ess ential to ba ck up the system sta te a s well as the filesystems on the
server volumes.
The Avama r client for Windows provides two plug-ins to give you additional options for
selecting what to ba ck up.
◆Wnd ows VSS plug-in
This plug-in provides full backups only, not incrementa l or differentia l, which is
required for disa ster recovery of Windows Server 2008, Windows Server 2008 R2, a nd
Windows 7. The d efault set tings for this plug-in are to create a disa ster recovery
ba ckup, and ba ck up all System Sta te a nd critical volumes. “ Ba cking up an entire
Windows client” on page 39 provides the steps to perform a backup with this plug-in.
Specific options for this plug-in are described in “ Windows VSS ba ckup options” on
page 184 and “ Windows VSS restore options” on page 185. “ Windows Server
2008/2012 and Windows 7/8 Bare Meta l Recovery” on pa ge 94 provides more
informa tion a bout performing a disa ste r recovery with the Windows VSS plug-in
backup.
Lea ve the Windows VSS option Create Disa ste r Recovery Backup selected, which is
the defa ult setting, because it is necessa ry as part of the full backup required for
disa ste r recovery. When you clear this opt ion, ba ckups a re much fas ter but a re not
valid for disa ste r recovery. You should only clear the checkbox for this option when
performing a ba ckup of a n Active Directory doma in controller. “ Windows Server 2008
and 2012 Active Directory backup and recovery” o n pa ge 125 provides more
information.
◆ Wndows File System plug-in
This plug-in ena bles you to s elect volumes, folders, or files for ba ckup. “ Backing up
volumes, folders, a nd files” on page 42 provides the steps to perform a ba ckup with
this plug-in. Specific options for this plug-in are described in “ Windows file system
ba ckup options” on page 178 and “ Windows file sys tem restore options” on
page 182.

Backup
Files excluded in Windows File System ba ckups
The Windows File System plug-in uses Microso ft Volume Sha dow Copy Services to perform
the ba ckups des cribed in “ Backing up volumes, folders, a nd files” on page 42. Open files
a re backed up s ince Avamar is backing up from the Shad ow Copy volume instead of the
origina l volume. However, a ccording to Microso ft best practices , Avama r skips th e files in
the following tab le by defa ult.
NTFS s oft links a re skipped by defa ult in Windows VSS ba ckups
Avamar Windows File Sys tem ba ckups us ing the Avamar Client for Windows will skip NTFS
softlinks (also known as symbolic links or symlinks). In addition, if an Excha nge,
Sha rePoint, or Windows S erver is configured to sa ve either data ba se files or log files to a
so ftlink pa th, b ackup will fa il. EMC plans to fix this in a future releas e.
Avamar does make an exception, as noted in “ Ba cking up a single directory or file on a
mount point, directory junction, or d irectory softlink” on pa ge 18.
Mount points , d irectory junctions, and d irectory symbolic links
Avamar supports b ackup and restore of individual files and d irectories on a :
◆ Mount point
◆ Directory junction
◆ Directory symbolic link
It is recommended tha t you re-create the mount point, d irectory junction, or directorysymbolic link before performing the restore. The conte nt is restored to the original loca tion
as long as the mount point, directory junction, or directory symbolic link exists. If it does
not exist, the n Avamar crea tes a directory path that ma tches the ba ckup path, a nd the
content is restored to a local directory with the lin
