If you are selecting “Delete Files” flag, please ensure that file verification is enabled at the Middleware level.
File verification will ensure that, files are written to the tape successfully. Still, we don’t recommend to use this flag in single LTO writing mode (no dual writing) because, some cases, tapes can go bad.
For example, 2.5 LTO 6 may takes hours to weeks to months to fill up based on the customer workflow.
If anything happens to the LTO tape while it almost full, you will lose the data.
