Tab: Database logging

Warning

d.ecs storage manager creates log files where the entries written to the reference table are logged in chronological order. As it is not possible to restore documents without the d.ecs storage manager reference table, these log files must be backed up regularly. An integrated, time-controlled backup function is provided in d.ecs storage manager for this purpose. This stores the log files (in compressed form) on the storage system and optionally in a directory (Copy logs to). The target directory must then also be backed up by a backup application.

Since this kind of logging is no replacement for a database backup, we recommend to create regular backups of the reference database of d.ecs storage manager.

Log path: Specify the path for the log files required for rebuilding the document reference table here.

Specify the path for the log files required for rebuilding the document reference table here.

Warning

Please enter a local path here. Saving the log-information via the network could result in problems, if the access to the network share is interrupted. If an entry cannot be written into the log file, then the storage is ended immediately. Additionally, this path must not be located under any storage-path (SnapLock area, CAS-areas etc.).

Destination pool: The log files are automatically stored in this pool. Enter the Pool ID of the storage pool where the log files are to be stored here.

Export log files: Specify the time interval when the log files should be written to the secondary storage here. The following time intervals can be selected

  • Hourly

  • Twice a day or

  • Once a day

Note

For security reasons you should select the shortest interval (Hourly). Log files are written to secondary storage only, if documents have been written to the secondary storage in the last time interval and thus new entries were created in the reference table.

Copy logs to: If this option is enabled, then the log files are not only stored on the storage system but also copied to the specified directory.

Note

If you are using a storage system without direct file access (such as TSM, Centera, iCAS), we recommend enabling this option to be able to access this information quickly in case of errors. You should create a backup of this directory regularly.

Retention time for logs (in years): Specifies the retention time for the IR files (index-recovery files)
