Sorry, another factor to consider is how many tapes you have available as well as whether you want/need to get tapes off-site (that can complicate things rather significantly and too many options start to affect decisions!)

Do you want/need the tape job to run daily, or would you be happy for it to just dump to tape at the weekend? (For example I do off-site backup copies anyway so aren't too fussed if I miss the occasional daily incremental to tape).

but my needs are slightly different to yours in so much as, because I have offsite copies anyway then I have no need to get tapes off-site daily (my "daily" tapes are purely to protect myself against local backup storage failure).
Dima P. wrote:That was the exact reason why we introduced the full backup option only in v1 of the GFS feature. GFS is used for long term archiving, so in most cases you would like to keep an ‘independent’ full copy of your data. Don’t get me wrong, we see and understand the need of ‘daily incremental’ option here.
Do you mean to say there is no way to use an incremental backup chain with a GFS full backup?
