INTRODUCTION
============
FileSafe V5.2.5-TD now supports all Mountain Network Solutions
mini-cartridge tape drives, including the IDE-interface FileSafe 8500.
Data compression and ECC error correction is offered in all formats.
The numerous enhancements provided by this software are detailed
in the following section.
NEW FEATURES
============
Extended NetWare Support
------------------------
This version of the software includes major new support for Novell's
NetWare 386, versions 3.10 and 3.11.
NetWare 386 features supported:
NetWare 386 Bindery Files
Netware 286 compatible Directory Rights
NetWare 286 compatible Directory and File Attributes
Preserves Last Access Date
Updates Last Archived Date
Netware 386 Directory Rights supported:
Create Directory/File
Erase Directory/File
File Scan
Modify Directory/File
Read from File
Write to File
Netware 386 Directory and Files attributes supported:
Directory File
========= ====
Options: System RO Read Only
Hidden RW Read Write
S Shareable
H Hidden
Sy System
T Transactional
A Archive Needed
RA Read Audit
WA Write Audit
NetWare 386 features NOT supported:
File level Trustees and Rights
Macintosh files (AFP)
Netware 386 Extended Directory and File attributes
Novell OS/2 HPFS, FTAM, NFS or Macintosh Name Space
Netware 386 Directory and File attributes NOT supported:
Directory File
========= ====
Purge P Purge
Deleteinhibit CI Copy Inhibit
Renameinhibit DI Delete Inhibit
RI Rename Inhibit
Files restored to a Netware 386 server will inherit the target
directory's rights and ownership.
Special note to Netware network administrators - This software is not
intended for use of upgrading Netware 286 to Netware 386. Files that
were backed up from Netware 286 and restored to Netware 386 will not
retain their original owners and trustees.
Special note to network Mach2 users - In some installations, it may be
necessary to insure that your Mach2 controller is using a higher priority
interrupt than your network adapter card. The lower the interrupt number,
the higher its priority. If you experience errors or very low data rates,
particularly when using the high-capacity TD101 format, make sure that
the Mach2 is assigned to a lower interrupt number than your network card.
VMM Support
-----------
A virtual memory subsystem is included to facilitate handling large
directory structures via either expanded or extended memory. In addition,
the speed with which these structures are built has been significantly
improved relative to earlier versions of TD software.
FileSafe 8500 IDE Drive Support
-------------------------------
Support for Mountain's FileSafe 8500 has been integrated into 5.2.5-TD.
Previously, a separate software version (5.2.4-IDE) was used for this
product.
On-Demand Formatting
--------------------
Regardless which tape format you use, 5.2.5-TD will automatically format
additional tape without user intervention whenever necessary to complete
an ongoing backup. You no longer need to be concerned with completely
pre-formatting tape cartridges.
DOS 5.0 Support
---------------
The AUTORUN utility has been redesigned to work correctly under DOS 5.0,
and the entire package has been extensively tested in the 5.0 environment.
CHKTAPE Extensions
------------------
Powerful new media analysis and data recovery capabilities have been added
to the CHKTAPE utility. These features allow recovery of selectively
backed up files which are otherwise inaccessible due to accidental over-
writing of the volume table, hard errors on the media, or failures during
the original backup process.
The CHKTAPE extensions may be invoked in two ways:
command line:
CHKTAPE /T
This invokes the CHKTAPE media analysis function, which displays
basic information about the current tape's format, voume table,
and data compression map. It is useful for obtaining a quick look
at an unknown data cartridge.
command line:
CHKTAPE /F[pathfilename][;pathfilename] /M# /V# /DDrive:path /S
This invokes the CHKTAPE file scanning (and recovery) functions.
The /M (mode) switch has the following meaning:
/M0 - This is the default, and will prompt the user whether or
not to recover each file found.
/M1 - This will cause encountered filenames to be displayed only;
it is used to generate a "directory" of recoverable files
for future reference.
/M2 - This will cause all files found to be recovered without any
further operator prompting.
Specifying scan range:
If the /V switch is supplied, then the decimal number following
this switch specifies the volume number to scan. If the /V is
not supplied, the user will be prompted to supply either a volume
number or an "override" segment range. Whether the scanned data
is treated as compressed or not will depend upon the volume table
entry if a volume is chosen; if the override is used, then the user
must specify whether or not to treat the scanned data as compressed.
Specifying source path/file selection(s):
If the optional pathfilename argument(s) follow the /F, then only
files whose full pathnames match these arguments (up to the last
character of the argument) will be processed. If no /F arguments
are supplied, all files encountered will be processed. Note that
wildcards (* and ?) are NOT supported in pathfilenames.
Specifying target drive and path:
The destination drive and path may be supplied on the command line
following the /D switch, or else the user will be prompted before
file scanning begins. If a destination path other than root ('\')
is supplied, then all recovered files will be placed in their
original paths below the supplied destination.
Special option:
The /S (slow scan) option may be used to attempt to recover files
which erroneously begin within the data area of a previous file.
This option results in significantly slower operation, and should
rarely be required.
Examples:
To recover all files under \DOS and its subdirectories from the second
volume on a tape, and to place these files on the D: drive's \DOS
directory, with user prompting before each file is recovered:
CHKTAPE /F\DOS /DD:\ /V2
To generate a directory of all files in the first volume on tape,
and to place this directory in the file V1DIR on the logged disk:
CHKTAPE /F /V1 /M1 > V1DIR
NOTE: File recovery only works on tapes which were originally written
using the SELECTIVE backup method. Damaged IMAGE volumes
CANNOT BE RECOVERED with this utility.
At least one space is required between each command line option
switch for proper parsing. Spaces should NOT be used between
the switch itself and its related argument(s).
