i have 3 jobs that i run with the software.  file server, exchange server, and sql server.  our file server requires 2 tapes now for a full backup because the compression is almost none.  the other incremental file server backups are getting decent compression.  the sql server gets decent compression for full backup, but the exchange server is also very little compression for a full backup.  can i adjust the compression level somehow?  

file server full backup compression:
1.08:1
1.06:1

file server incremental backup compression:
2.57:1
2.93:1
2.69:1
2.93:1
2.58:1

sql full compression:
2.73:1
2.61:1
3.16:1
2.92:1
2.94:1
3.14:1

exchange full compression:
1.11:1
1.09:1
1.08:1
1.12:1
1.12:1
1.21:1

Your tape drive usually has hardware compression enabled by default.

If you are not getting full compression on you file server backup,you need to check if hardware compression is enabled for that job.


Remember that WHAT you backup affects the compression ratio.

Files such as jpg ,mpg ,pst .exe zip do not compress very well as they are all ready in a compressed format.

mostly the files are xls, doc, ppt and probably some jpg.

the job is set to hardware backup.

ppt doesn't compress

excel I think is about 1.1

.doc can br pretty high 3 :1,but if there are embedded images,that can change

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Look at users .pst also.  People are packrats and tend to leave email file attachments in the email (either on the Exchange server or in  a .pst) Some house keeping may be in order.  Easier said than done, I know.  On some networks that I managed, it was easier to get funding to buy more robust backup solution than it was to get users to archive email and clean out their home directories.

One thing I have done is do a "search" by file size in Windows Explorer for files 100 MB and larger.  You may find some .exe files for program installation.  You will be surprised what people will save on the server.  Simply burn them off to DVD and delet from server.

Hope that helps.

sorry pgm554, i thought i had relied to you earlier, but i must have imagined it or something.  thanks for the additional input drawlin.

i had a program on my home computer that shows the folder sizes and statistics and all, but i couldnt remember the name.  its windirstat from sourceforge.  i just ran it against the directory on the file server and here are the top numbers.

xls 12.8%
mdb 7.9%
dat 7.0%
zip 5.5%
ppt 5.5%
jpg 4.9%
doc 4.4%
iso 3.5%
dwg 2.7%
[none] 2.3%
pst 2.2%
pdf 2.1%

xls 12.8%  Some compression
mdb 7.9% no compression
dat 7.0%   no compression
zip 5.5%   no compression
ppt 5.5%  no compression
jpg 4.9%   no compression
doc 4.4% good compression
iso 3.5%  no compression
dwg 2.7%  no compression
[none] 2.3%
pst 2.2%   no compression
pdf 2.1%   no compression

Roughly 17% can compress ,the rest is little to none.

So it sounds about right.

i guess that makes sense why the incremental is so much more compressed.  doc and xls are the files that get hit most.  most of the rest of those are probably only accessed and not changed.  thanks for the help guys.
