Replacing a library When a library fails, or when the library robotics card must be changed, the replacement will have a different serial number from the original. To assign it the same pools, mapping, etc. as the original: NOTE: While the virtual tapes are in the firesafe, scheduled backups for those tapes will not occur. 1. Make a note of all pool configuration information for pools associated with the library to be replaced. 2. Delete all pools associated with the library (see Deleting a Copy Pool). NOTE: Deleting the pools automatically moves all virtual cartridges from within the pool to the firesafe. 3. Unmanage the physical library to be replaced (see Managing and Unmanaging a Destination Library). 4. Replace the library or robotics card. 5. Manage the new physical library (see Managing and Unmanaging a Destination Library). 6. Manually recreate the storage pools associated with the new library using the information written down at the beginning of this procedure. The virtual tapes that were moved into the firesafe will automatically return to their previous locations. Deduplication Issues Symptom The VLS is not deduplicating the backup jobs. Possible causes Solution The VLS does not free up storage on a cartridge until: • At least two full backups of the same policy exist on different cartridges • The delta-differencer has processed all of the backup sets on the cartridge • The cartridge is physically full Consider using cartridges that are smaller than the sum of your daily backup jobs so the cartridges deduplicate sooner.
