Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.

When to delete restore files

When to delete restore files

If you repeatedly run the same archecker table-level restore, you must clean up the archecker table-level restore working files and tables from the previous runs. These working tables refer to acu_ tables in the sysutils database that are created during an archecker table-level restore. The archecker table-level restore working files and tables are kept after an archecker table-level restore completes in case these files and tables are needed for diagnosing problems.

You can remove the working files and tables by explicitly running the command archecker -DX or by using the -d option when you run the next archecker table-level restore command. The -d option indicates that all files and tables from the previous run of archecker table-level restore are removed before the new restore begins.

ontape example: archecker -tdvs -fschema_command_file
onbar example: archecker -bdvs -fschema_command_file
