line and has up to 18 lines of help.
~Full Backup:Daily Incremental:Cleanup Incremental
Full Backup
A Full Backup backs up all the files in the folder(s) you specify,
usually all the files on a partition of your hard disk. It often
takes a long time and many backup disks because a hard disk stores
a lot of information. It should be done initially and then from
time to time whenever a clean copy of everything on the hard disk
is desired. Between full backups, you should run daily
incremental and cleanup incremental backups.
To run a full backup, click on 'Full Backup' under the 'File' menu.
~Daily Incremental:Full Backup
Daily Incremental Backup
A daily incremental backup backs up only those files which have
changed since the last time you backed up your hard disk. This is
the most commonly used type of backup because it's quick and you
can therefore do it daily. Before you run a daily incremental,
though, you must run a full backup.
To run a daily incremental, click on 'Daily Incremental' under the
'File' menu.
~Cleanup Incremental:Full Backup:Daily Incremental
Cleanup Incremental Backup
After many days of running a daily incremental, your incremental
backup set will fill up. Then, it's time to run a cleanup
incremental, which backs up all the files which have changed since
the last full backup. After the cleanup incremental, you can
continue with daily incrementals until the backup sets fill up
again and you run another cleanup incremental. Eventually, enough
will change on your hard disk since the last full backup so that
it's best to run a full backup instead of a cleanup incremental.
To run a cleanup incremental, click on 'Cleanup Incremental' under
the 'File' menu.
~Archive Bit:Cleanup Incremental:Daily Incremental
Archive Bit
TOS version 1.4 or newer will set the "archive" bit on a file
whenever it is modified. This includes modifying a file with a
database and any time a file is created. A file which is moved by
copying and then deleting the old file will have its archive bit
set, too.
Normally, The Vault does not back up according to how the archive
bit is set, but does clear the bit when it backs up a file. When
the "Use Archive Bit" flag in the "Options" menu is set, The Vault
will back up files with the archive bit set and files with a new
date when running an incremental backup. If a file it backs up
has an old date so that it would not have been backed up without
the archive bit, The Vault changes its date so it would have been.
This way, it will be backed up on subsequent cleanup incrementals.
Note that this option is not available with TOS 1.0 or TOS 1.2
~Split Files:Split Threshold
Split Files
Sometimes, the files you want to back up are larger than will fit on
one floppy disk. The Vault then splits them into two or more files
across subsequent backup sets, giving each one a unique name based on
the original file's name. The Vault uses the same base name, but adds
a new extender telling which part of the file it is. For example, if
The Vault splits a file "BIG.BIG" across three disks, it creates files
called "BIG.A01", "BIG.A02" and "BIG.A03". If "BIG.Axx" already
exists, where xx are two digits, The Vault will try other letters
until it finds one which is free. For example, if you have a real
file called "BIG.A34", The Vault would call the split files "BIG.B01",
"BIG.B02" and "BIG.B03" instead.
When The Vault doesn't split files, you can restore its backup sets
using any standard file copy program. But when it splits a file, you
need The Key (the restore program for The Vault) to restore it.
Because of the inconvenience of split files, you can give The Vault a
split threshold, so that it will never split small files.
~Full Copy:Full Backup:Split Files:History File
Full Copy
Full Copy is like Full Backup except that The Vault never splits
files, writes the history file, changes the date on a file when using
the archive bit, or checks disk labels. You are also only allowed
one starting folder on a full copy. It is useful when you just
want to copy data, such as making up disks for a user group or a
friend.
To run a full copy, click on 'Full Copy' under the 'File' menu.
~Incremental Copy:Full Copy
Incremental Copy
Incremental Copy is like Full Copy except that only those files
created or modified since a date and time you specify will be
copied.
To run an incremental copy, click on 'Incremental Copy' under the
'File' menu.
~Input Parameters:Folder Selection:File Selection:History File:Starting Folder
Selecting the Input Parameters
The Input Parameters dialog box allows you to specify which files
you want backed up. It has three parts: in the left-hand window
are the folders to back up. In the right-hand window are the
folder selection masks for the selected starting folder in the
left-hand window. This lets you specify some folder to not back
up. To change the starting folders and folder selection masks,
click on the items in the windows and use the buttons 'Add',
'Insert', 'Edit', 'Delete' and 'Clear', which apply to the current
window.
Below that is the backup history name, which you can type in by
hand or use the mouse to select, and the file selection
masks which, like the folder selection masks, let you tell The
Vault to back up certain files and not others. The Vault will
back up all files matching the file selection masks in folders
matching the folder selection masks.
~File Selection
File Selection Masks
File selection masks let you select which files to back up. Use
*.* to include all files. '*' matches any string of zero or more
characters, '?' matches exactly one character, and other
characters match themselves. Thus, *.PAS would match only those
files whose type is '.PAS', and *2.? would match all files whose
name ends with '2' and whose type is a single character.
If you give more than one mask, The Vault uses them from left to
right. For example, *.pas *.c backs up all the '.PAS' and '.C'
files. A mask preceded by an exclamation point (!) excludes the
matching files. For example, *.* !*.BAK backs up all files except
the '.BAK' files. Each new mask adds to or subtracts from the set
of files specified by all preceding masks. For example, *.*
!TEST.* *.C starts with all files, then removes those matching
'TEST.*', then adds back all files matching '*.C'. Note that
'TEST.C' will be backed up by these rules.
~Folder Selection:File Selection:Starting Folder
Folder Selection Masks
Folder selection masks let you select which folders to back up. Use
'.' to include all subfolders of the starting folder. You select them
with the file selector the way you select a starting folder: select a
starting folder, click on the "Folder Selection" window and then on
the "Add" button. Each Folder Selection Mask is simply the "tail-end"
of a path-name. Therefore, you cannot select a folder selection mask
which is above the starting folder to which it applies. For example,
if your starting folder were E:\R\ and you wanted E:\R\DOCS\ to be
backed up, then that folder with the file selector and "DOCS\" would
appear in the window. You could not select "E:\" with the file
selector because that's above "E:\R" in the folder tree.
As with File Selection masks, if you give more than one mask, The Vault
uses them from the top down. If you click on the "Exclude" button, the
given mask excludes the matching folder. Clicking on the "Fl Only" button
A mask makes the mask not apply to any of its subfolders.
~Output Parameters:Backup Set
Output Parameters Dialog Box
The Output Parameters dialog box lets you select the backup set
name and starting volume number. Enter the requested information
from the keyboard.
The backup set name should consist of at most eight
alphanumeric characters. The starting volume number should
generally be 1.
On a copy, this box also lets you select an output folder. You
may select any
