The only thing that was still confusing was that I needed to used a convert SQL clause to retrieve the data as text although it was still Hex encoded just no longer binary. I'll mark this as an answer once I get the project to the next stage. Thanks to all those who thought about this problem :) No I have to put my money where my mouth is and make it happen but at least I have a workable plan now. I can't report on historic data as it is still compressed but this is no big deal as the users are interested in reporting on trends over the last week or so. There could be an initial growth in my overall storage size as the file system tried to compress already compressed data. I plan to do the reporting as a scheduled task and if someone really wants to find and restore an archived email guess who they are going to ask! The search routing for locating messages in the backup doesn't look through this compressed data in any case. I know this could potentially have an unknown performance impact as I have moved the compression / decompression from one place to another but who knows it may get better :) Overall performance isn't a big deal as there is almost no online user interaction with the backup database. That is to say it is a varbinary(max) column with FileStream enabled and the actual data is stored directly in the NTFS file system outside of the database.mdb file.Īfter much reading of best practices and "never do this's" I have enabled NTFS file compression on the FileStream data folder and turned off compression in the Backup application. The RFC822_msg column that I'm trying to decode is actually a FileStream column. I think I have come up with a workaround solution. ![]() I have tried to open the resulting file with 7zip and Windows built in ZIP. ![]() As each hexadecimal digit represents four binary digits (bits), it allows a more human-friendly representation of binary-coded values. The database table also has a column named "ZIPCOMPRESSION" and is 1 or 0 depending on wether compression is on or off.ĭoes anyone have any ideas how I can read the compressed text. Hexadecimal numerals are widely used by computer system designers and programmers. I'm Using Visual Studio 2008 and SQL Server 2008 R2 and the backup software is Policy Patrol. ![]() Either my little program doesn't decode it properly back into a binary file or I haven't yet guessed what the backup software has used to compress the text. I figure that I must first decode it back into a binary file then decompress it. (not the same email as above but it is going to be very similar)ĠxCD396B8C23C959E599BB7DCCED240B977B26DCD47995DBDBBB69BBDBAFB17B6 The compressed hex string starts like this.

The MD5 message-digest algorithm is a widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed as a 32 digit hexadecimal number. Paste/Type encoded hex data in input box Reverse lookup, unhash, decode, or 'decrypt' MD5 (128 bit).Read more about Hex at Wikipedia How to use Hex Decoder?įollow the steps given below to decode hex: In mathematics and computing, the hexadecimal numeral system is a positional numeral system that represents numbers using a radix of 16.
