MetaReader is a tool to read the contents of snapshot (.snp) and failoverlog (.fol) files generated by Couchbase enterprise backup tool 'cbbackupmgr'. This tool is designed for debugging purposes.
The only dependency is cbflag which can be install using
go get github.com/couchbase/cbflag
Clone the repo and then run go build/install
To dump the contents of the snapshot file for all vBuckets use the snapshot command
metareader snapshot -p /repo/archive/2019-01-25T10_03_15.064487Z/beer-sample-1da173e4511d0bfa50e47c146dfe340a/data
To dump the contents of the failoverlog file for all vBuckets use the snapshot command
metareader failoverlog -p /repo/archive/2019-01-25T10_03_15.064487Z/beer-sample-1da173e4511d0bfa50e47c146dfe340a/data
You can filter vBuckets in both commands by using --filter which takes a
comma separated list of vBuckets to display (e.g. 0,1,2,3,4,5), it also will
accept ranges (e.g 0-10,30-50), ranges are inclusive.
