In DOS there was the ability to verify a singular files integrity by
using chkdsk c:/file.dos......The result indicated if the file integrity
was so.
There was also the ability to set in the Autoexec.bat set verify=ON -
which made sure that EVERY file that you copied you did not need to use
the verify option C:\file.dos C:\temp\file.dos /v 

My questions are 
1. Is there a global set verify=on in Linux?
2. Is there the ability to verify a single files integrity as above with
a similar command such as chkdsk

The reason I ask is that I recently lost my home directory and I had
KDAR backing up the /home directory every week to an NFS drive. When I
came to restore the archive the files header was reported to be
corrupted. Also as a backup I copied with Konqueror the /home directory
to an NFS drive and some of the files are aslo now not readable due
corruption.

I have made an Enhancement report to both Konqueror and KDAR that they
include a verify option like most backup programs. Over many years I
have seen backups unable to be restored because verify was not turned
on. Now its happened to me.I understand the file system in Linux is far
superior in its disk I/O but I dont want to waste time backing up if I
cannot ensure the files are intact.
