Re: DLT Tape life

It says here that they have a "30 year guaranteed archival life":

Re: DLT Tape life

Hi,
there will be no absolute answer, as it depends for example on:
1. How often a tape is used
2. What condition is it stored in
Also how important is the data to you.
A single tape that is used in a open office environment to back up daily will survive shorter than a tape that is part of a backup set used once a month, stored in good conditions.
If data retrieval is critical I would perform multiple backups.
We tend to change our tapes every 3 years

Re: DLT Tape life

Hi,

It is either,

30-year guaranteed archival life.

Durability up to 1,000,000 head passes or an average of 10,000 loads/unloads.

With Regards,

Siva.

10,000 loads/unloads is for LTO and not for DLT !

Re: DLT Tape life

I'm not sure if you mean how many backups you can make on one tape, or if you mean how long will the tape physically last with recoverable data once a backup has been made to it (shelf life).

We use a DLTtape IV in a DLTvs80 drive.

HP recommends the tape be replaced after 100 full backups.

As far as shelf life, I don't know.

Re: DLT Tape life

If the tapes are stored correctly 30 years is the archival life of the tapes.

However, DLT media is intended for 250 uses... one write and one verify is considered 2 uses.
