Hello Stefan,
Regarding the first question "We have got existing tapes with written data and we like to keep this data but would like to use new labels (barcodes).
I have read http://support.veritas.com/docs/190875 but I am not sure if BE overwrites the data on the tape ",
- please note that when barcode is applied to a tape, only the label will be changed from normal label to that of barcode label. This will not overwrite the existing data on the tape.
However, to be on safer side, you can first test it. For that take a small backup on a normal tape. Once data is present on it, put a barcode on it. Enable barcode rules in Backup Exec. Now as barcode rule is enabled, instead of inventory, perform Initialize and scan on it. This should read the data on the media and catalogs will be seen.
Regarding another question of "So what happens if I switch the MSL6030 and BE to barcode scanning, put barcodes on the existing tapes, insert them, initialize, scan and run an inventory"
- As said above, when barcode rule is enabled, you need to perform Initialize and Scan and not Inventory job. This is because, when barcode rule is enabled, you need to perfom Initialize and Scan as it should be done. Inventory job will fail.
The third question of "We have got LTO2 and LTO3 Tapes.
Is there anything we have to consider when using barcodes?
(We have got barcodes for LTO2 and LTO3)"
- You do not have to specifically consider anything when using barcodes for these tapes.
About the last question "Is it possible to mix tapes: Tapes with barcodes and tapes without barcodes?"
- Usually it is better if you use all the tapes having either barcode rule enabled or normal tapes.
Hope this answers your querries.
Regards
