The following steps are performed during an Oracle Server backup job in Database and Archived Log backup modes.
CloudBacko Pro PDIC will run on the first backup job that falls on the corresponding day of the week from Monday to Friday.
To minimize the impact of the potential load of large number of PDIC jobs running at the same time, the schedule of a PDIC job for each backup set is automatically determined by the result of the following formula:
PDIC schedule = %BackupSetID% modulo 5 or %BackupSetID% mod 5
The calculated result will map to the corresponding day of the week (i.e., from Monday to Friday).
The PDIC schedule cannot be changed.
Backup set ID: 1594627447932
Calculation: 1594627447932 mod 5 = 2 That is Wednesday
In this example:
Although according to the PDIC formula for determining the schedule is %BackupSetID% mod 5, this schedule only applies if the previous PDIC job was actually run more than 7 days prior.
Under certain conditions, the PDIC may not run strictly according to this formula. For example:
To minimize the possibility of index related issues affecting backups, each time index files are downloaded from and uploaded to backup destination(s); the file size, last modified date, and checksum is verified to ensure index file integrity.
