The PureCM database files are stored in the location specified when installing PureCM (typically PureCM\data). The following files will be found in the directory:
Table 16.1. PureCM Data Files
|Data File||tdf||Contains all non-binary data|
|Binary Data File||tbf||Contains all binary data|
If you want to backup the PureCM data files using a backup program such as NTBackup on Windows or 'tar' on Unix see the section called “Backing Up the PureCM Data Files”. Although this is the simplest solution, it is recommended that you create database snapshots and back these up. Snapshots are compressed and therefore take up less space than the actual data files.
The PureCM snapshot files are stored in the location specified when installing PureCM (typically PureCM\snapshots). The following files will be found in the directory:
Table 16.2. PureCM Snapshot Files
|Snapshot File||tds||A compressed copy of the data files which can be restored|
If the PureCM database you are backing up is large then you typically wouldn't want to create more than one or two snapshots a day. While the snapshots are being created other users cannot use the tool, and the amount of storage required for many snapshots will soon mount up.
If you want to perform many backups during the day, a better solution is to backup the log file as described in the section called “Applying the Log File”. To recover the database you would first recover the snapshot and then apply each log file as described in the section called “Applying the Log File”.
The PureCM log files are stored in the location specified when installing PureCM (typically PureCM\logs). The active log files will be found under the logs directory. Any archived log files will be found in the subdirectory 'archive' (e.g. PureCM\logs\archive).

|Log Commands File||tlf||Contains the log of all commands|
|Log Pre-Image File||tpf||Contains the binary data used by the commands file|
