I use .. incremental backups via a batch file that is
calling arj, in combination with a scheduler that starts the
whole thing at 7 a.m., but I have added one important step:
encrypting the backup.
I might be a tad paranoid - the "Church" of Scientology is
after me, and in such cases one can't be too cautious - but
I really believe that all private communications should be
stored encrypted. I also use a PGP-disk as my mail
repository.
=== fwd 2 ===
Here's my batch file for incremental backups & encryption:
@echo off
set path=c:\utils\backup;e:\backups\h-drive
set tz=met-1dst
c:\utils\arj\arj32 a -r -hm0 -i2 -h# -jm -b1
-x!c:\utils\backup\h-exclude.txt e:\backups\h-drive\h- h:\*.*
c:\utils\backup\pgp23 -e -w e:\backups\h-drive\h-*.arj Karin Spaink
I'll break up the last two lines:
c:\utils\arj\arj32
That's where my arj32.exe resides;
a -r -hm0 -i2 -h# -jm -b1 -x!c:\utils\backup\h-exclude.txt
The switches for arj.exe:
a = archive
-r = use recursive directories
-hm0 = to manage huge file lists
-i2 = provides a combined percentage and bar progress display
-h# = append current date/time string
-jm = select high size reduction
-b1 = backup changed files and reset archive bits
-x[x] = exclude the files named in [x]
e:\backups\h-drive\h- h:\*.*
Backup target and backup source
This results in files in the format H-010223.arj (for 23 Feb
2001). In the last line, this file is encrypted
(conventional encryption), using the key stored in the
backup directory:
c:\utils\backup\pgp23 -e -w e:\backups\h-drive\h-*.arj Karin Spaink
-e = encrypt file
-w = wipe original
That's it. It's executed in well under five minutes, using a
P600.
