couchtool is a simple backup/restore tool for Apache CouchDB and databases compatible with its API. The on disk format used is one file per document/attachment. This was chosen so that the backups are easily rsnapshot-able, without making a full copy on each snapshot.
npm install -g couchtool
Show database info:
# Print db size and document count
couchtool dump http://localhost:5984/some_db
Create backup:
# Dump all documents in ./some_db/ directory
couchtool dump http://localhost:5984/some_db
Restore from backup:
# Read and soreall documents from ./some_db/ directory
couchtool restore http://localhost:5984/some_db
By default the the docs will be split in 10 directories docs.0/ to docs.9/. If you want to change the number of directories you can use --buckets :
# Split documents in 100 directories
couchtool --buckets 100 restore http://localhost:5984/some_db
You can use the buckets command to find appropriate bucket number for large databases:
# Show number of documents in each bucket
couchtool buckets http://localhost:5984/some_db
Also the documents can be stored gziped on disk with --gzip :
# Gzip documents and attachments on disk
couchtool --gzip restore http://localhost:5984/some_db
