Exchange 2007 logs

Exchange 2007 running on SBS 2008. Log files are 35gig and I want rid of them so that I can configure circular logging. I do not want to go to the botther of installing an exchange aware backup program if I can avoid it. Having said that if that is the only safe way of clearing them then I will do it. Can I just enable circular logging and that will clear them automatically and safely. I am aware that circular logging wasnt recommended up till Microsoft changed their minds with 2010 which has it enabled by default.

However, if circular logging is enabled, you can recover data only up until the last full backup.
If you confider your data to be valuable then just take the full exchange backup..

So the windows backup does an Excahnge backup?. Are you saying Microsoft have by design made Excahnge unrecoverable in Windows SBS 2011 because by default it uses circular logging. I dont use any of those backup solutions I use Shadow Protect. I will probably install Veritas just to do a single backup as I dont trust the Microsoft Wizard. After that I want to configure circular logging. I have an extract program which extracts PSTs from an exchange database so would use that in the event of a server failure. I presume with circular logging the emails received are stored in the database and the recovery program I have just needs the edb and stm files not the log files.

Log files are required incase when you do not have a good edb and stm files.
If there is a good backup of edb n stm then logs are not that important.

For taking Exchange Full Backup, use any of the above third party backup solutions.
If you are planing for veritas then its a good option too.

So it is the case that the windows backup doesnt backup excahnge?. I suspected so as I have now found out that the previous IT person had scheduled a windows backup every night. If so I will have to install Veritas as you say. What a mess.

Yes,go for VERITAS its the best option for getting Exchange Full Backup.

Note- In previous versions of Exchange,when they were running on windows 2003 server then using " NTBACKUP " we can take the full backup of exchange database.
NTBACKUP is not there in windows 2008 n later.
