We were discussing how we would backup our data from the various environments we will have and I was hoping someone could chime in with previous experience in this. My primary concern about our cluster is that we would like to be able to recover anything within the last 60 days so having full backups both on tape and through distcp is preferred.
Out initial thoughts can be seen in the jpeg attached but just in case any of you are weary of attachments it can also be summarized below:
Prod Cluster --DistCp--> On-site Backup cluster with Fuse mount point running NetBackup daemon --NetBackup--> Media Server --> Tape
One of our biggest grey areas so far is how do most people accomplish incremental backups? Our thought was to tie this into our NetBackup configuration as this can be done for other connectors but we do not see anything for HDFS yet.
