LTO4 tape life cycle

Jump to solution

Hi all,

I use LTO4 tapes for backup (quite intensive) not for archive. How often shall I change LTO4 tapes? What is your experience about LTO4 life cycle?

 

Thanks a lot

Hi quiz,

according to the vendors or LTO drives and media you should not exceed 250 full overwrites. If you're using it extensive this will happen somewhere in a 24-60 month time frame. By default Data Protector will enforce this 250 overwrite limit (Media Pool options) and also mark the tape Fair/Poor after 36 month.  I usually adjust this time to 60 month. Be careful when you re-format existing tapes, since this information will be lost.

If you usually append to a tape until it becomes full a full write is the number of overwrites.
