I currently backup a bit more than 16TB to an LTO3 library and don't find
it that painful. I use AMANDA and break the data down into bite-size
chunks. AMANDA handles spreading these chunks out over the whole backup
cycle, so that each night's backup is about the same size (and so takes
about the same amount of time). Each "chunk" gets a full dump once per
cycle and incrementals in between.
Is a lot of your data static and/or in "small" files? Would your backup
method work if the RAID held many large files, most of which were
modified each day?
Define small and large. On the volumes I was referring to, files range
from few KB text files to several GB data files. And AMANDA could be made
to work with the situation you describe, as long as the you can physically
move the amount of data you're talking about in your backup window.
