They requested a backup (datapump) of 1.5 TB but from Dec 15, 2021. The Job for fileretention had already expired.
The volume was as FULL and with 25 TB of data. 1) I tried first with bextrack and it's too slow. 6 hours without any file. 2) try using bconsole restore Regexp. I end up with status OK after 10 hours, but with 0 files recovered. 3) Well, I filled myself with patience and went to search "bscan". Which lasted 40 hours to complete the recreation of the catalog. And I managed to restore the requested 1.5 TB file in just 4 hours. After this desperate experience but with the expected results. The following questions arise. 1) Is there a way to make the bscan run faster? I had always worked with lto6. But lto7 is already different, it's 25TB of data with a FULL tape, I assume that the search time increases. 2) Is there any other way to create the Files in the catalog but only indicating the Jobid? Just imagine a BSCAN in lto8 or 9 3) What can be the best path for these scenarios? Due to this experience we increased the times in fileretention and jobretention in the most critical servers. -- ############################# # Sistema Operativo: Debian # # Caracas, Venezuela # #############################
