Barcode Label & Library Partition

Created: 02 Jul 2014 • Updated: 02 Jul 2014 | 4 comments
This issue has been solved. See solution.

I have following backup scenario.

BE.2014 is backing up 5 servers to IBM TS3100 Tape Libary, 5 days in a week. I have to keep at least weeks of data, then they get overwrite

Example:

SERVER1 = MONDAY / SET1 = DISK1
SERVER2 = TUESDAY / SET1 = DISK2
SERVER3 = WEDNESDAY / SET1 = DISK3
SERVER4 = THURSDAY / SET1 = DISK4
SERVER5 = FRIDAY / SET1 = DISK5

I have configured Library Partitions for 5 Slots, and bind the each day job with each slot Like

SERVER1 = MONDAY / SET1 = DISK1 = SLOT 1
SERVER2 = TUESDAY / SET1 = DISK2 = SLOT 2
SERVER3 = TUESDAY / SET1 = DISK3 = SLOT 3
SERVER4 = TUESDAY / SET1 = DISK4 = SLOT 4
SERVER5 = WEDNESDAY / SET1 = DISK5 = SLOT 5

I have implemented barcodes to the tape cartridges and now library is recognizing the cartridges via there barcode label. My question is that currently I insert catridges according to label in the library like Monday = Slot1 , Tuesday = Slot2 and so on

Is there any way I can insert cartridges in any slots (randomly) and BE picks the tape according to the bar code label and write data according to the job?

If you want to be able to put your tapes into any slot, then you got to get rid of partitions.  Just use media sets and target your jobs to these media set.

For the initial run of your jobs, you need to put the tapes in the scratch media set so that they are overwritable.  After the job used them, they would be placed in the targeted media set.

BTW, you should not be too concerned about which backup set goes onto which tape.  See my article below

After readint eh article you pointed, I will prefer to have my manual scheme using Library Partitions and stick each job with the corresponding slot, Also its easier for restore purpose to put 'correct' tape for sure.

Be aware that when you use partitions and you do not have sufficient ovewritable tapes for the job.  It will fail because BE will not fetch tapes from another partition and there is no way to introduce overwritable tapes if there are no empty slots in the partition.

Ok thank you for your valueable advise :) I will make a note for that.

One last qustion, Do I have to do SCAN the library everytime when I put old tapes (old backup set cartrdiges like week 2, week 3)  so that new backup may be overwritten on it (I have OP set to none)?

As I can see that backup job auto overwrite data on older tapes with new data , even if I donot do scan. So why to do scan or inventory ?
