When you 'copied' the directory, did the DATE of the directory change?? 

Thats probably why it didn't back anything new up.. 

And thats why incrbydates shouldnt be relied upon always - should always
do normal incremental backups as well

Hi,
I enabled the journal service for drive F: of a test windows-based TSM
client. Here is the interesting test results:
1- total filesystem size:14GB
2- used space: 370MB (pdf, doc, exe and ... other ordinary files)
3- I enabled journal
4- snapshot image backup was successful
5- the .jbbdb file in journal directory got populated
6- I copies a directory from c: for f:
7- the size of .jbbdb file changed (means journal service is working)
8- I performed a incremental-by-date for image backup
9- NOTHING was backuped!

Do you have any explanation for this?

Regards,
Mehdi
