Hi,
We intend to use long term tape backup with tape out at offsite.
Assuming that we have 2 sets of tapes and retention of 1 year. This will result in alternate months of data at onsite and offsite at any given time.
Colocation will be used, so based on my understanding the write period must expire at 1 month to achieve offsite ready at the end of every month.
After tape out to offsite and returned back to the Tape library with the previously set write period expired, can the tape be appended with the new month's data without overwriting the previous months' backup that is still within the retention period?
Thanks!
