I have a MCS-7835 call manager server,with 80GB HDD capacity,in which nearly 60gb space is occupied with call manager soft and lots of log file for last 1yr.Can anone suggest me which files are to be deleted for freeing the HDD space.
If log records were never deleted from the transaction log, the logical log would grow until it filled all the available space on the disks holding the physical log files. At some point in time, old log records no longer necessary for recovering or restoring a database must be deleted to make way for new log records. The process of deleting these log records to reduce the size of the logical log is called truncating the log
This said, it is very important to keep a backup of your system at any stage. Hence installing and taking backup with BARS should be your first step.
Truncating of logs would not be deleting any CDR records as such.
