We have exchange 2003 on a windows small business server 2003. We have disk space problem and when i looked at exchange server folder there are about 70 gigabytes of data. priv1.edb, priv1.stm, pub1.stm, pub1.edb. These files cost 35 gigabytes to us. I think these are the main files. Is there a way to carry this data? There are log files. Every of them cost 5 megabytes but when i sum them it's 35 gigabytes. What will happen if i delete these files?

Do not delete the transaction logs. Are you running full, online backups? If not, please do as soon as possible. This will clear any committed logs. http://technet.microsoft.com/en-us/library/aa996125(EXCHG.65).aspx Overview of Exchange Server Backup Methods How much free space is available on the drives?

We have a storage system and i took a backup of exchange server. Now we have about 30 gigabytes of free space. I found this link, he explains online backup with ntbackup. I'll look at the link you've given. Thank you.
