XADM: EDBUTIL Uses Exchange Bin Directory for Tempdfrg.edb

MORE INFORMATION

Edbutil reads from the source .edb file and writes to the destination .edb file. After the source .edb file reaches end-of-file, the destination is copied over the source .edb file.

If the Exchange Server Bin directory does not have adequate space, EDBUTIL continues to read from the source .edb file, even though EDBUTIL cannot write to the destination .edb file. This causes the final .edb file to appear corrupt and unusable.

For example, Exchange Server is running on drive C, which has 100 MB of free disk space; drive D has 5 GB free space. Priv.edb is 2 GB. If you run EDBUTIL without specifying the Tempdfrg.edb path, Priv.Edb will be truncated to about 100 MB.

To assure Tempdfrg.edb is placed on the drive with adequate free space:

• Use the /T<DRIVE:>PATH switch:

  EDBUTIL /D /ISPRIV /TC:\MYDIRECTORY\TEMPDFRG.EDB

  The tempdfrg.edb can be <any name>.edb
