Hello Tilo, Thanks for your help. I will try to implement solution 1.) in the next days and will get back to you with the results.

Relying on regular checking of backups: You would need to create two scripts as substitutes for save and restore. The save/restore scripts would have to start a compression tool like gzip/gunzip such that it reads/writes from/to a pipe and these scripts would have to start the original save/restore programs with the parameters they were called them self. You would change the NSR_HOME setting in your MaxDB configuration to point to the scripts, instead of the original save and restore. You would have to create a link called mminfo in that directory to point to the original mminfo. You would have to set NSR_USEOUTPUT to NONE and would thereby losing any check for NetWorkers error messages especially during backup. You should therefore use the compressed backups only for data backups and not for log backups and you should check all your data backups using DBMGUI or recover_check. 2.) Do not use backup media of type NSR You could backup into normal pipe media (not of type NSR) and write scripts, that do the complete compression and backup/restore from/into the pipe them self. But there is no advantage to variant No 1. In both cases you should test your backup/restore procedure using a test system. And if you encounter any problems or if it worked straight away ... keep us informed.

Our systems are running on HP-UX 11.11/11.23 with various versions of MaxDB databases. What do you mean by creating some scripts? Do I have to substitute the save/restore executables or do I have to substitute some scripts on the MaxDB side. Thanks and best regards, Tobias. -----Ursprüngliche Nachricht----- Von: Heinrich, Tilo [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 9.

If the result is worth such effort, the next question would be, what OS you are using. As your are using R/3, you are a regular SAP customer. Therefore I have to advise you to open a OSS message at SAP regarding your question.

Unfortunately I found no description of an exact implementation and no information regarding a (un)successful implementation. Therefore I have the following questions: Can anybody provide any implementation details for using compression with MaxDB and legato networker and has anybody implemented this successful? Thanks in advance.
