How RecoverEDGE
Works RecoverEDGE is a crash recovery tool that enables quick and easy recovery from any data loss, even if a system will no longer
boot. Plus, it can be used for normal system maintenance, such as defragmenting filesystems, repartitioning drive space, swapping hard drives, and more! RecoverEDGE is
available for SCO Unix, SCO OpenServer, Linux, and Unixware 7.1 . This following describes the features that are common to all three. For more information, please see our press releases on RecoverEDGE
for Linux and RecoverEDGE for UnixWare 7.1
. Without
RecoverEDGE If you had a total system failure (i.e., your system would not boot), and you didn't have
RecoverEDGE, you would resort to the following procedure to recover your data:
- Identify and correct the cause of the failure.
- Reconfigure the hard drive(s) and reinstall a base operating system using the standard UNIX install procedure.
- Install any device drivers needed to access your tape drive.
- Configure and mount any additional filesystems.
- Restore your backups.
- Shut down and reboot.
Reinstalling a base operating system and any needed device drivers is usually a very time consuming process. More than half of all recovery time is usually spent during this phase. With RecoverEDGE
On the other hand, if you used RecoverEDGE,
restoring your system would become easy:
- Identify and correct the cause of the failure.
- Boot from the
RecoverEDGE disks.
Select "One-Touch Restore" to automatically reconfigure your filesystems and restore from tape.
Shut down and reboot.
With RecoverEDGE, system recovery takes just a
few seconds to prepare the filesystems and start the restore. Then, after a reboot, your system is totally operational. You don't need to worry about hard drive size changes, either, since
RecoverEDGE can automatically scale your
filesystems to fit! Intelligent Crash Recovery RecoverEDGE
is designed to adapt to your system, not the other way around. When making a
boot diskette, it will attempt to shrink the diskette copy of the UNIX kernel by removing line number information and the symbol table, so a larger kernel can be used than would normally fit. You may also configure
specific parameters to make your boot kernel more efficient. During filesystem diskette creation, RecoverEDGE
automatically detects the number of filesystems, number of hard drives, etc., so it knows exactly what steps must be taken to
repair your system.It detects and ignores any mounted CD-ROM's, NFS-mounted filesystems, and RAM disks. Plus, it provides you with a complete system report so even a novice system administrator can see exactly how
the system is configured. During recovery, it can automatically recreate (and resize, if necessary) your filesystems, and restore your entire system. If you wish, you may make any manual adjustments as well, making
RecoverEDGE a
powerful reconfiguration tool.A comprehensive Hard Disk Status Report can be viewed or printed. This report details all aspects of your system drive and host adapter configuration. Easy Boot-Recovery RecoverEDGE has a menu interface that can automatically rebuild all your filesystems. There is no guesswork as to when a
particular program must be run, or what its command-line arguments are, because RecoverEDGE runs the programs for you! If you do wish to make manual adjustments, simply refer to the RecoverEDGE Hard Disk Status Report
for the appropriate information. about your original system, and change the configuration as desired.If your primary drive has lost its parameter table or boot record, RecoverEDGE allows you to simply rewrite those without
destroying any data, making such repairs extremely quick and painless. Remote Boot Recovery RecoverEDGE
allows boot-recovery from machines that must use a remote tape device to access the archive. During diskette creation a separate network diskette is created. When booted from the
RecoverEDGE media, TCP/IP can be started, and tapes
from remote systems can be read. RecoverEDGE
also supports crash recovery controlled from a serial or TCP/IP connection. Whether you administer systems that are hundreds of miles away or just downstairs,
you will want to learn about this feature! Filesystem Modifications
RecoverEDGE can be used to resize any of your filesystems or
swap space in a fraction of the time it would normally take. RecoverEDGE
also offers a Root-Only restore option for reconfiguring only the root filesystem without affecting any other drives. The "One-Touch" restore option also allows you to restore only the primary hard drive. On UnixWare 7.1 and Linux, RecoverEDGE
allows you to restore any single hard drive, not just the primary one. Of course, it can restore all of them automatically, too! Where Can I Buy RecoverEDGE? Recover
