+ - Ask Slashdot: switching to open source tape backup, what about old tapes?

Submitted by m.ardito
m.ardito (2655241) writes "I work in the IT staff of a small company, since 2006 we used proprietary (HP openview data protector) software to backup lan/servers data: both incremental and full backup jobs end up being copied to Ultrium/LTO tapes.
Now we would like to switch to some good open source software replacing proprietary software but keeping that backup schema above, I'm thinking of bacula, mainly (suggestions?). We don't want to keep proprietary software around, but may need to read its tapes in the future (at least 1-2 years).
Now what I'm asking slashdot is: is there any easy and reliable way to convert those tapes or make (eg) bacula read them, or... other ways? What would you do pals? Are we forced to keep proprietary software working until we don't need its tapes anymore, while we switch to other software, or there are other workflows we can follow? I can think to restore those data with proprietary software to a temporary location and backing them again to (newer) tapes with (eg) bacula, but there are fulls and incremental jobs in most tapes, i can't figure out an easy and reliable way to to this. What would you do?"
