D.4.4.2 data/backup Subdirectory
The backup subdirectory stores files that Data Management subsystem components processed and require no further processing.
That is, they are considered to be in a final form after successful processing.
- Transformers back up files that they receive and create.
- Loaders back up files that they finished loading. Each file in the backup directory appears in a subdirectory with the date as its name. The name is in the format YYYYMMDD, where YYYY is the four-digit year, MM is the two-digit month, and DD is the two-digit day.
The IMC component, runIMC.sh, cleans up the backup subdirectory. The
IMC's configuration file defines the number of days that backup files age before
removal. The following table references the files that the system writes to the backup
subdirectory, by component.
