Overview and Features

Enterprise Windows Client

The COSmanager Enterprise Windows Client for Windows 2000/XP/2003 V3.1.1 allows the integration of Windows hosts into the COSbackup policy based backup environment and COStask job scheduling environment. The management and delegation of the backup policy and job scheduling policy is UNIX or Linux centric. The backup and task environments can contain any number of UNIX, Linux or Windows 2000/XP/2003 hosts. These hosts and their resources (tape drives, filesystems, applications, etc) are then accessible by any other host in the environment.

EWC (Enterprise Windows Client) was previously known as EBC (Enterprise Backup Client).


New features in EWC 3.1.1

The features of EWC V3.1.1 when used as a Backup Client are:

The features of EWC V3.1.1 when used as a Task Client are:

A detailed description of EBC and its features and benefits can be found in the COSmanager EBC User Guide V2.2.

Technical Notes: Using EWC 3.1.1

This section contains some technical notes and tips about EWC for Windows 2000/XP/2003 V3.1.

Upgrading from Enterprise Windows Client V3.1

You are now not required to uninstall EWC V3.1 prior to installing EWC V3.1.1. Instead you just install EWC 3.1.1. The installation process will deal with stopping the communications services (COSserver and RSHD) and uninstalling the appropriate components of EWC 3.1 before it proceeds with installing EWC 3.1.1. By doing this you will retain license keys and allowed hosts configuration so you will not need to re-license and re-configure afterward.


Upgrading from Enterprise Backup Client V2.1/V2.2/V2.2.1

You cannot have more than one version of the EBC [EWC] running at the same time. You must uninstall EBC V2.x prior to installing EWC V3.1.

Note
 Note

After uninstalling EBC it is possible that some files are not completely removed. Ensure the following files, folders and entries have been removed before installing EWC V3.1.1. If you fail to remove these files errors may result when running backups or scheduled task jobs:

It is also recommended that you remove the following Registry keys before you install EWC 3.1.1:


Licensing

EWC for Windows 2000/XP/2003 may be issued with a temporary license for use in trials or demonstrations. Temporary licenses have an in-built expiry date. You must obtain a permanent license or a new temporary license from your COSmanager distributor to keep using the product after the expiry date. Licensing EWC will fail if you attempt to license the product using a key that will expire within 5 days.

Note
 Note
In order for a valid permanent EBC/ETC license key to be supplied you must provide both the hostname and type of Windows installation, WORKSTATION or SERVER.


UNIX to Windows connectivity

Connectivity, Unix to Windows, Windows to Unix, or Windows to Windows can either be via:

The COSmanager Remote Server for EWC Windows service runs as the SYSTEM user. In order for the Enterprise Windows Client to communicate with COSbackup on the UNIX host, the UNIX host must have a host entry in the COSmanager hostinfo table for the EWC host. This is achieved by entering the Windows host in the Host Information table, Config > COSmanager configuration > Host information .

The Remote Shell Daemon on Windows runs as the SYSTEM user. In order for the Enterprise Windows Client to communicate with COSbackup on the UNIX host, the UNIX host must have a SYSTEM entry in the cosmos <WINNT>/rhosts file for the EWC host. This is achieved by entering the Windows host in the Host Information table, Config > COSmanager configuration > Host information . If the OS version is set to a Windows OS, this entry will be automatically added when you run Remote > Allow access .

UNIX hostname must be able to be resolved to their associated IP address. If DNS is not used or is not properly configured for hostname resolution to occur, then you must appropriately populate the file <WINNT>/system32/drivers/etc/hosts.


COSmanager Remote Server for EWC (COSserver)

Unlike RSHD, COSserver listens and communicates via a single port only, port 9002. This simplifies firewall setup. For further information on COSserver, see Technical Note 214 - COSserver Information.

Changes to the Windows hostinfo table are not read dynamically. The hostinfo table is only read during startup of the COSmanager Remote Server for EWC service. Restart the COSmanager Remote Server for EWC service to pick up any changes to the allowed hosts.


COSmanager Remote Shell Daemon (RSHD)

Changes to the <WINNT>/rhosts file are not read dynamically. The rhosts file is only read during startup of the COSmanager Remote Shell Daemon service. Restart the COSmanager Remote Shell Daemon service to pick up any changes to the rhosts file.

The COSmanager Remote Shell Daemon service does not pick up the last line in the rhosts file if it is not followed by a carriage-return (CR). This may only become apparent if the file is edited manually. Ensure the last entry is followed by a carriage-return.


Backup and Recovery

A backup item cannot define a directory with a single quote in it. The item can be created, but it will fail if it is run. Also you cannot specify a restore directory with a single quote in it. This will cause the recovery to fail.

Exclude file patterns (-x and -X options) and select file patterns (selected ntcpio backup methods) cannot contain spaces. The patterns will effectively be ignored. Instead substitute each space in your file pattern with question mark.


Incremental backup of filesystems

The directory (or folder) being backed up must be writable. If the directory is not writable, a full backup of that directory will be performed.

The COSbackup term Incremental Backup actually refers to the generally accepted term Differential Backup.


Generating an index

You cannot generate an index for UNIX/Linux specific backup methods on a Windows removable media drive. The index must be generated from a UNIX/Linux removable media drive. Re-generating an index for a Windows specific backup on a UNIX/Linux removable media drive will cause the backup data to sent across your network to the Windows host.


System State backup

System State is a collection of system-specific data that can be backed up and restored. The System State data includes the registry, the COM Class Registration database, and the system boot files. For servers, the System State data also includes the Certificate Services database (if the server is operating as a certificate server). If the server is a domain controller, the System State data also includes the Active Directory directory services database and the SYSVOL directory.

If your COSbackup Master is running version 3.2.6 or earlier, you will need to add the following backup method before you can run a System State backup of a Windows host: 1. Select COSbackup configuration > Maintain other tables > Backup method. 2. Select Maintain > Add. Backup method system state Description Backup Windows NT system state Format ntcpio Backup command FSsysstate $Options Multipart support? no Uses STDOUT? yes Index support? no Remote support? yes Run on host file_host Press Accept to save this backup method.


Controlling Open File Manager

If your COSbackup Master is running version 3.2.6 or earlier, you will need to add the following backup methods before you can control OFM running on a Windows host from your backup job: 1. Select COSbackup configuration > Maintain other tables > Backup method . 2. Select Maintain > Add . Backup method sync OFM Description Syncronize OFM from St Bernard running on Windows Format Backup command ofm sync$Options Multipart support? no Uses STDOUT? no Index support? no Remote support? yes Run on host file_host 3. Select Maintain > Add . Backup method unsync OFM Description Unyncronize OFM from St Bernard running on Windows Format Backup command ofm unsync$Options Multipart support? no Uses STDOUT? no Index support? no Remote support? yes Run on host file_host


Restore with Open File Manager

When you restore files and directories to a Windows host that has OFM running, you must pause or stop OFM first. This is because the restore uses ntcpio and will cause OFM to syncronize before any files are restored. If you do not pause or stop OFM first, it is common to see messages in the recovery log like: ntcpio: Cannot create directory ./abc

Caution
 Caution!
Before restoring files to a Windows host that is running OFM, ensure OFM is first paused or stopped, via Control Panel > Services, or via OFM > System > Stop.


Excluding files from backup

You can set up a standard set of files to be excluded from your Windows backups. By default “*/pagefile.sys” is excluded. You can add extra exclude file patterns, one pattern per line, by editing the file <install folder>/db/exclude.
