I'm running Exchange Server 2013 that was inherited or not properly deployed and planned:
Windows Server 2008 R2
C:\ 200 GB [OS - 70GB remaining]
D:\ 1.95 TB [Mailbox DB - 50GB remaining free disk space]
L:\ 200 GB [Logs - 30 GB remaining free disk space]
P:\ 100 GB [Page file - 10 GB remaining]
So If I run the Exchange backup to truncate the log files now during the business hours, does it can cause any mail flow impact ?
Does the D: drive of the Database will run out due to the very large transaction logs being committed to the Exchange database ?
Note: The D: drive cannot be extended anymore to 2 TB due to NTFS - MBR partition
