Backup Professional Frequently Asked Questions

Here you will find answers to the most commonly asked questions about Backup Professional. If you dont see an answer, please .
  Q: Can Backup Professional backup my Oracle 8 database using hot archive mode?
  A: The Backup Professional Oracle module effectively backs up Oracle 7, 8 and 9. There are many ways to configure this module. It can be used in conjunction with hot archive mode, cold archive mode and replica mode. Additionally, this module will capture the Oracle redo log file when it is completed and immediately append it to tape or put it on a virtual disk archive for safe keeping. The database is backed up in a very coherent state suitable for restoring. Backup Professional understands the virtual space inside of the Oracle database files and removes this so the archive media does not contain this. This greatly improves restore time and saves space on tapes and disks.
  Q: Can Backup Professional backup my Oracle log files every 15 minutes as they are created by the Oracle system?
  A: This capability is included within the Oracle Module. This capability is also available with Backup Professional DataSweep™ technology. It looks for the creation of a log file by Oracle which has all transactions that have transpired in the last 15 minutes. This log file is backed up and appended to the tape every 15 minutes as each one is created.
  Q: Can Backup Professional backup my Informix, Progress or Sybase databases?
  A: The before command of Backup Professional is used to put the database into hot archive mode. Following this a backup is done of the database itself, then the after command is run which takes the database out of hot archive mode and puts it into regular mode. Because Backup Professional can so easily append backups to a tape, it is preferable to set up a database backup as a special profile. Then this can be scheduled at any time. Keep in mind that when you do this it is advisable to exclude the database directory from the system backup since it is usually done as a separate task.
  Q: Can Backup Professional be used to backup a network consisting of only three Windows 98 machines?
  A: No, Backup Professional requires a server. At the time of this writing we support nine server platforms. NT will be coming in the near future. Windows 95/98 is not one of the servers. The backup model used by Backup Professional is that of a client server and there are no current plans to support Win95 or Win98 being used as a server. However, there are plans underway to support Windows 2000 as a server, so please check our server list frequently.
  Q: Will Backup Professional support my IDE tape drive?
  A: Backup Professional will support the IDE tape drive if you can read and write both rewind and no rewind device using the tar utility shipped with your platform. In this case, you will be unable to use advanced positioning and fast seek. The advanced positioning is used for positioning two different file sets on a tape for either backup or restore. Quick seek is used when restoring a file to quickly seek to this file.

With an IDE tape drive the restore process will be slower because there is no quick seek capability. Therefore, if you have not already purchased a tape drive, we suggest you purchase one that is fully SCSI compatible.

  Q: Will Backup Professional support my Onstream tape drive?
  A: This tape drive will run under Windows NT and will require special drivers. In addition, there is a version that runs under Linux. Even though the tape is said to be SCSI, to the best of our knowledge it is not a fully compliant SCSI 2 compatible tape drive. It requires special drivers to handle rewriting data and the like. Therefore, this tape drive can only be supported in low level mode. In low level mode we do not support advanced tape positioning or a fast seek restore. This tape drive will require a call to our technical support staff to set up some special tape command adjustments in your master initialization file.
  Q: Do you support my particular tape library?
  A: Backup Professional will support all SCSI 2 and/or SCSI 3 compliant tape libraries. This includes jukeboxes which have separate SCSI ID for the changer arm as well as autoloaders whose changer arm is addressed using LUN 1. (logical unit number 1)

We have certified and tested Backup Professional with auto changers from all the major manufacturers including ADIC, Overland Data, Quantum, Sony, Seagate, Hewlett-Packard, and Qualstar.

Backup Professional has over seventeen different auto changer drivers that it can interface with. In addition, the Backup Professional can be customized to interface with just about any set of auto changer drivers. Therefore, it is very easy to configure Backup Professional for auto changer drivers that do not ship as part of the product.

  Q: Does Backup Professional support SMTP alerts?
  A: Backup Professional can be customized to include SMTP alerts by modifying the reporting command which is invoked after a scheduled backup has completed. This could be completed in a fairly short period of time by a knowledgeable shell programmer.
  Q: Does Backup Professional backup open files under Windows NT/2000 or Win 98/95?
  A: Backup Professional Agents now have a built-in enhanced open file manager. This enhanced open file manager allows Backup Professional to backup up open files as if they were in a frozen state. Additionally, Backup Professional Agents will lock the files before they are backed up, so that no other software can change them until the backup of that file is complete. Several levels of locking are provided. Registry files which are in constantly in use by the system are backed up using a different method, that allow individual hive, branch and key restore. You can create a list of files which are considered okay to skip and will not generate an error message.
  Q: Does Backup Professional have a module to backup Microsoft Exchange Server under Windows NT?
  A: Backup Professional Microsoft Exchange Module is now available and can properly backup Microsoft Exchange Server. This can be done with a minimum of down time to the Exchange Server (5-10 minutes on most systems).

This is done by creating a custom backup profile. The before command of the backup profile temporarily shuts down the exchange server database engine. Then the exchange server data directory is backed up. Following this, the after command restarts the exchange server. This provides for a complete backup of the exchange server with a minimum of down time.

A restore profile can be custom created to restore the entire exchange server should the need arise. Like the backup profile, the before and after commands stop and then start the exchange server database engine.

Also, please note that Backup Professional will soon be available with hot file backup. This is described in the previous FAQ. This allows Backup Professional to get a backup snapshot of the Microsoft Exchange Server product as well as the other files on the hard disk without ever having to shutdown the exchange server database engine. This allows 24x7 use of the Microsoft Exchange Server.

If you want to be able to restore an individual mailbox at any given date and time using Backup Professional there are techniques available to accomplish this by restoring to a separate location.

  Q: Does Backup Professional backup Novell NDS under Novell 4.0 or 4.x and 5.x?
  A: Backup Professional does not specifically backup the NDS subsystem. However, you can run a utility using the before command of a Backup Professional profile and unload the NDS database into a frozen state. This frozen state can be backed up and then when it is restored a likewise utility can be used to reload this.

As a rule of thumb, the NDS takes care of itself with other servers on the network.

It is our current plan for Backup Professional to work with the open file manager module for Novell 4.0, 5.0 and this will allow a backup of the NDS system.

  Q: Does Backup Professional backup Novell binary under Novell 3.x?
  A: Yes, Backup Professional does backup this binary. During the backup when backing up the binary files, it goes through the binary on a record-by-record basis and backs each record up even though the binary could be changing while the backup is occurring.
  Q: Can I administer Backup Professional from my PC
  A: Backup Professional can be administered from anywhere in the network. The administration can be done using the character interface from a telnet session. If you desire to use the X interface to administer the product you will need to install an X server on your PC such as the Humming Bird product or Vision FS. These have been tested and run fine under Win95, Win98 and Windows NT.

Backup Professional also runs through SCO Tarantella. This allows any browser on any PC or other machine access to the full server X Window interface.

  Q: Does Backup Professional support multiple streaming tape drives simultaneously?
  A: Yes, in fact Backup Professional can be backing up multiple clients at one time to multiple tape drives. Each backup is an independent session. This allows for maximum throughput. The limitations of Backup Professional in this regard is only limited by the number of tape drives that you can install on your server.
  Q: I have three Backup Professionals installed each on its own machine with its own tape drive. Can I administer all three from a single site?
  A: In the current release of Backup Professional, each server is an independent entity. It has its own database and task scheduler. However, all three can be administered from a single site using X windows by displaying the output from the session on each of the three servers to a single site. Additionally, all the reporting and printing of all the servers can be consolidated so that they go to a simple source.
  Q: I have used some other backup products and they did not restore to DLLs that are in use by Windows NT. I must then manually copy these in from a DOS floppy.
  A: Backup Professional will restore DLLs to running system of NT. If the DLL is in use Backup Professional will note this and on the next reboot install it before Windows NT is even up and running.
  Q: Does Backup Professional support a Solaris Intel Client?
  A: Backup Professional does support Solaris Intel 2.5, 2,6, 7.0 and 8.0. This distribution is the same as the generic System V Release 4 (SVR4) release and the ftp download file is called "svr4_cnt".
  Q: Does Backup Professional support Free BSD client?
  A: Yes, there is a Backup Professional client support for Free BSD 3.3 or higher.
  Q: Does Backup Professional support Open BSD?
  A: Backup Professional supports a client for BSDI. However, you can install the Linux compatibility package under Open BSD and use the Linux client of Backup Professional. You must have the "linux_base" package installed and you must put the keyword linux_enable=YES in the rc.conf file.

Additionally, you must run the following command:

brandelf -f Linux /usr/bp/bin/bkup

This works for Free BSD 3.3 or higher.

  Q: How does Backup Professional behave when it restores its own database on top of itself while it is running?
  A: This has been tested and works fine with a few exceptions. Since the task table is restored obviously the old tasks are no longer valid and they are detected and canceled. Therefore, if you are running a backup and restore the entire Backup Professional directory you will notice that your tasks will disappear in the task table. Backup Professional will behave the same as it did at the point when the backup was taken.
  Q: Does Backup Professional backup Banyon Vines?
  A: No, not at this time. It is our understanding that Banyon Vine runs under a BSD version of Unix. We do support the BSDI version of Unix but at this time we do not support the Free BSD version of Unix. At some point in the future we do plan to have a Free BSD client and at that time we do expect this will backup a Banyon Vines server.
  Q: My Demo has expired, can I get a Demo Extension?
  A: In most cases the demo evaluation period is adequate time to evaluate the product. However, in extenuating circumstances it is possible to extend your evaluation period. You will need to go in theHelp->License Management and generate a demo extension request.
  Q: Do you handle files over 2 Gigabytes?
  A: On operating systems that support files over 2 Gigabytes, we support this. This includes but is not limited to Solaris Intel X86, UnixWare 7, Sun Solari , Linux, HP UX 11 and higher, AIX 4.2 and higher, DEC Alpha and SGI 6.x with 64 bit CPU's.
  Q: Do you support Macintosh or OS/2?
  A: No, these clients are not supported. Currently there are no plans to support these clients. We suggest the Dantz Backup Solution for the Macintosh and the IBM solutions which are based on Sytos for the OS/2 machines.
  Q: I have a Unix Client I do not see on the list of supported clients. Can Backup Professional be ported to this client?
  A: Upon special request and for a porting fee, the Backup Professional client component can be ported to other Unix platforms. This would be done for an order involving a large number of clients for which no existing client port has been done. Call our sales staff for details on the process and costs involved.
  Q: Does Backup Professional support data encryption?
  A: This feature is on the road map for the 2.1 release of Backup Professional. It is possible to integrate Backup Professional with secure shell during data transport so that all data is fully encrypted during transport. This is especially useful for a WAN or backups via the internet.
  Q: Does Backup Professional support by SAN or switched fabric SAN environment?
  A: Backup Professional can backup SANS using one of two techniques. First and fastest is to backup a SAN logical unit using its built-in and fast raw device partition backup features.

A special profile is created to backup each SAN logical unit or set of units. This SAN backup profile turns on the double buffering feature of the backup engine. This forces a multi-process, multi-threaded backup using shared memory and double buffers for the maximum possible speed. Finally, this profile is then scheduled so that it occurs at regular intervals.

This method allows bare metal recovery of the SAN disk sub-system and is the fastest possible backup and restore.

Backup Professional can backup a SAN system if the SAN driver is running under one of the nine server platforms that we support. Many such systems run a Solaris, BSD or Linux version of Unix under the hood. If the SAN system is running Linux as its primary operating system, you can install the Backup Professional server and get a native backup of the SAN disk system.

The second method is to backup the SAN using a file-by-file method. This can be done from either Unix or Windows NT/2000. Though this is not as efficient as a native SAN backup, it does give you file-by-file backup and restore capability as well as the ability to archive versions as they change over time. This is a critical and necessary piece to your backup strategy.
