For archiving material there is no way to compromise.
For short-term projects we work all times on raid5, so your data allways can be recovered if any harddisk failure might occur.
Longterm projects are regularly backed up by modern LTO technology, that´s why you can feel save with us. There´s nothing worse than a data loss after a brilliant shoot!
Our data safety still could give you worldwide footage from begining of the 90ties.
