Exchange 07 backup software and log files

We have one Exchange 07 server with less than 200GB mail store located on the SAN volume with ISCSI
Are using Backup exec for Exchange option for backups and backing it up to another iscsi disk.
Backup speed a very but typically only 300mb/min so  many times it fails for vireos reasons (some time we have to cancel it when it still running in the morning)
1.      When backup is not finished few days in a row we have too many log files. What is the proper and safe way to remove few days old log files?    
2.      Is there a better backup for Exchange software in the same price range as Symantec?

What is the proper and safe way to remove few days old log files? - You can move any logs older than 8 hours to be on the safer side .... or best to Dismount the database after production hours and move any logs older than 2 hrs :)

Is there a better backup for Exchange software in the same price range as Symantec? - SYmantec is one o fthe best ... what is the version of Windows ?

You can try with Comvault\Arcserve or if its Windows 2003 or Windows 2008 R2 you can try using native Windows backup.

In my experience pretty much everything is better than any of Symantec's products.
Backup Assist is my current preferred tool of choice. It is cheap and does the job (as it uses the native backup tools).

You shouldn't move or remove any of the log files, only the backup should do that. If you move the logs then subsequent backups may fail and if the database goes off line or the server is rebooted the database may not mount.

If you need the space, then you can compress the files to get the space back.
DO NOT COMPRESS THE DIRECTORY. Select the oldest files, go up to about an hour old at most. Then right click and choose Properties, Advanced and compress. That will give you space back, with little performance impact and still allow the backup to remove them correctly.

Simon Butler (Sembee)ConsultantCommented:
Why do you need granular restore?
I haven't used any of those kind of features in all of the time that I have been using Exchange.

Furthermore the method that Symantec use for granular restore isn't supported by Microsoft.

Turn up Deleted Item rentention will cover most things, if a user has deleted content from longer than 30 or 60 days then they can wait for an RSG restore.
Split the database up in to multiple databases (you can have four on Exchange 2007) and the amount of content to restore is minimal.

native windows backup is not an option as I am need granular restore option - Ohk so 3rd parties are also good :) ..... but MS and everyone will always recommend you Online backup.

What is the White space available in this 200GB database ?

Simon,
it looks like you never seen a public folder deleted by  users acidental click.
I can restore public folder  in 2 min which you won't find anywere in deleted . So granular restore is a must for me.

If the user deleted the public folder then they can undelete the folder.
I have been working with Exchange for some time, and not once have I failed to recover something without having to use any of the "brick level" or "granular restore" features that Symantec offer - although I guess that is why they justify the cost of the product (which is almost as much as Exchange).

leop1212: What is the number of days the emails are retained as per Database Email limit ?
Also you can try to Divide Mailboxes with adding some new Databases.

@ leop1212 enable the Dumpster Always on registry key (key varies by Outlook version) and then the user who Deleted the object can recover the object using Recover Deleted Items.
Same goes for any other object deleted in Outlook.

You can also use PFDAVADMIN or MAPIMFC to get the content back.
This ancient thread from Technet forum explains the process.
