Looking at moving up from 9840 20 Gig level technology to 200/300 gig tapes to backup AIX & NT and was looking for some views on the pro's/con's of LTO2 vs 9940.
The management lean is towards LTO2 as it is cheaper and more "politically correct" at the moment.
I came across the following worrying statement:
"LTO tapes will not read past errors once they are encountered on a tape. That means that one error on one tape can ruin your entire restore process. 9840 / 9940 technology is designed to read past errors and to use extensive error correction technology to recover the data and continue with the restore process."
Given the above, has anyone seen/experienced any problems like this or otherwise with LTO/LTO2 technology and what has been peoples experience with LTO/LTO2 as a backup media choice. Speed? Reliability? Rehitch delays? Anything else?
