Strange difference in file size when copying LARGE file..
Hi, Im trying to take a database backup. one of the files is 26 GB. I am using cp -pr to create a backup copy of the database. after the copying is complete, if i do du -hrs on the folders i saw a difference of 2GB.
The weird fact is that the BACKUP folder was 2 GB more than the original one!
when i did du -hrs * inside each of the 2 folders and compared the output, i found the culprit. it was a file temp.dbf which was 26 GB on the source(original) folder and 28 GB in the BACKUP folder. I tried the copy procedure twice and I am getting the same result.
does anyone have any explanation for this. please let me know. I want to make sure everything is right here in the copy.
PS:- Solaris SPARC 23 BIT.
Thanks

refile
refile(1mh) refile(1mh)
Name
refile - file message in other folders
Syntax
refile [ msgs ] [ +folder ] [ options ]
Description
Use the command to move the specified message from the current folder to another folder. You can refile messages in more than one folder
by giving multiple folder names as arguments.
If you do not specify a message, the current message is refiled. You can refile a message other than the current message by giving its
number as a msgs argument. You can also refile more than one message at a time by specifying more than one message number, or a range of
message numbers, or a message sequence. See for more information on sequences.
The current folder remains the same unless the -src option is specified; in that case, the source folder becomes current. Normally, the
last message specified becomes the current message. However, if the -link option is used, the current message is not changed.
If the Previous-Sequence: entry is set in the file, in addition to defining the named sequences from the source folder, will also define
those sequences for the destination folders. See for information concerning the previous sequence.
Options
-draft Refiles the draft message, or the current message in your folder, if you have one set up. You cannot give a msgs argument when
you use this option.
-file filename
Moves a file into a folder. This option takes a file from its directory and places it in the named folder, as the next message
in the folder. The file must be formatted as a legal mail message. This means that the message must have the minimum header
fields separated from the body of the message by a blank line or a line of dashes.
-help Prints a list of the valid options to this command.
-link
-nolink Keeps a copy of the message in the source folder. Normally, removes the messages from the original folder when it refiles them.
The -link option keeps a copy in the original folder, as well as filing a copy in the new folder.
-preserve
-nopreserve
Preserves the number of a message in the new folder. Normally, when a message is refiled in to another folder, it is set to the
next available number in that folder. The -preserve option keeps the number of the message the same in the new folder as it had
been in the old.
You cannot have two messages with the same number in one folder, so you should use this option with care.
-src +folder
Specifies the source folder to take messages from. Normally, messages are refiled from the current folder into another folder.
However, you can take messages from a different folder by using the -src +folder option to specify the alternative source folder.
Examples
The following example refiles messages 3 and 5 in the folder
% refile 3 5 +records
The next example files the current message into two folders:
% refile +jones +map
The next example takes message 13 in the current folder and refiles it in the folder. The message remains in the current folder as well as
appearing in the folder.
% refile -link 13 +test
The next example takes a message from the folder when it is not the current folder, and places it in the folder
% refile 3 -src +test +outbox
Profile Components
Path: To determine your Mail directory
Folder-Protect: To set protections when creating a new folder
rmmproc: Program to delete the message
