How high is demand for mirroring the FASTA/ subfolder of ftp://ftp.ncbi.nlm.nih.gov/blast/db/ ? I'll be happy to consider adding it to bio-mirror.net. On the other hand, it is a large data chunk, and will add to network copy load which now is stretched for the blast-format tar files. We have almost continuous ftp copying from ncbi:/blast/db/ now due to the almost daily data turnover, ftp timeouts, and such. Those who want source data could instead use the Genbank dataset -> fasta, at a lower cost. E.g. only a few Genbank/WGS subsets are updated daily, whereas the whole 18 GB blast wgs.fasta is updated daily. Rsync is a nice tool, but has a much higher server side CPU cost than FTP. Those of you running into rsync errors at NCBI would probably have better luck using an FTP mirroring tool. - Don Gilbert -- d.gilbert--bioinformatics--indiana-u--bloomington-in-47405 -- gilbertd at indiana.edu--http://marmot.bio.indiana.edu/
