The problem is when the encryption on, the amount of data should be the same
as when it runs without encryption - or have I misunderstood something ?

If I make a backup of a node without encryption, and it sends e.g. 20 GB of 
data - the the amount ought to be the same, if I delete all data on the TSM 
server, and then tries to do the exact same backup with encryption enabled (of 
course remembering to change the client dsm.opt file and restart the dsmc 
application)

Regards,

Brian

Problems with encrypted backup






Hi,

I've tried to solve this issue before without luck. I'm trying to make a
backup with encryption on a new node/client. The node is registered on the
server, and the first login from the node (using dsmc and a simple dsm.opt
file only specifying the nodename, passwordgenerate and the server) has
been made (where it asks for nodename and password). Then I quit dsmc
again.

My first backup dsm.opt file (with encryption)

NODENAME TSM-MYTEST1
PASSWORDACCESS GENERATE
TCPSERVERADDRESS 172.16.7.136
DOMAIN D:
schedlogretention 15
DateFormat 2
COMPRESSION ON
Encryptkey Save
EXCLUDE *
EXCLUDE.DIR "D:\BilledArkiv\Network Trash Folder\...\*"
EXCLUDE.DIR "D:\BilledArkiv\TheFindByContentFolder\...\*"
EXCLUDE.DIR "D:\BilledArkiv\ThevolumeSettingsFolder\...\*"
EXCLUDE.DIR "D:\BilledArkiv\Temporary Items\...\*"
INCLUDE.Encrypt "D:\BilledArkiv\...\*"
INCLUDE.Encrypt "D:\Bogholder\...\*"

I assume, that I have to set EncryptKey to SAVE - otherwise the scheduler
won't be able to make backups.
A backup using these options and running "dsmc i" gives this result:

Total number of objects inspected: 149,290
Total number of objects backed up: 25,189
Total number of objects updated: 0
Total number of objects rebound: 0
Total number of objects deleted: 0
Total number of objects expired: 0
Total number of objects failed: 0
Total number of bytes transferred: 8.40 MB
Data transfer time: 0.49 sec
Network data transfer rate: 17,247.31 KB/sec
Aggregate data transfer rate: 21.27 KB/sec
Objects compressed by: 0%
Elapsed processing time: 00:06:44

If I then change dsm.opt to the options below (thereby removing
encryption):

NODENAME TSM-MYTEST1
PASSWORDACCESS GENERATE
TCPSERVERADDRESS 172.16.7.136
DOMAIN D:
schedlogretention 15
DateFormat 2
COMPRESSION ON
EXCLUDE *
EXCLUDE.DIR "D:\BilledArkiv\Network Trash Folder\...\*"
EXCLUDE.DIR "D:\BilledArkiv\TheFindByContentFolder\...\*"
EXCLUDE.DIR "D:\BilledArkiv\ThevolumeSettingsFolder\...\*"
EXCLUDE.DIR "D:\BilledArkiv\Temporary Items\...\*"
INCLUDE "D:\BilledArkiv\...\*"
INCLUDE "D:\Bogholder\...\*"

And delete the old data in my TSM Server (using "del filespace") - and
then makes a new backup using "dsmc i" - the the result is:

Total number of objects inspected: 149,290
Total number of objects backed up: 144,088
Total number of objects updated: 0
Total number of objects rebound: 0
Total number of objects deleted: 0
Total number of objects expired: 0
Total number of objects failed: 0
Total number of bytes transferred: 87.28 GB
Data transfer time: 1,394.87 sec
Network data transfer rate: 65,618.49 KB/sec
Aggregate data transfer rate: 5,848.74 KB/sec
Objects compressed by: 11%
Elapsed processing time: 04:20:49

What is going wrong ?? The TSM server is running 5.2.2.3, and the client
is 5.2.0.6 ...
