ArangoDB - Backup and restore all data

Question

My aim is to create the arango database dump (with all the users and passwords, permissions, databases, collections, roles and so on) and then make a full restore of this data on the other arango server (that was installed from scratch and empty).

I am using the one-node configuration, arangodb version is 3.4.4 [linux] .

On origin I make a dump of every database:

USER=root
PASSWORD=***
for db in $(arangosh --server.username "$USER" --server.password "$PASSWORD" --javascript.execute-string "db._databases().forEach(function(db) { print(db); });")
do
  arangodump --output-directory /tmp/dump/"$db" --overwrite true --server.username "$USER" --server.password "$PASSWORD" --include-system-collections --server.database "$db"
done

Then I move the created folders to the empty arangodb server on this server go with:

arangorestore --input-directory "/tmp/dump/_system/"
arangorestore --input-directory "/tmp/dump/collection/"
arangorestore --input-directory "/tmp/dump/collection2/"
...one by one 

The result if very far my expectations, I just get the collections in _system database for the root user (no other users, no databases).

What am I doing wrong? How can I make the full backup and restore?

Thanks in advance.

Answer 1

arangorestore needs to be told to which database to restore the data to. This can be achieved by providing the --server.database option in the same way as it can be done for arangodump . If no value is provided for --server.database it will default to _system , meaning the subsequent invocations of arangorestore will each overwrite the previous data in the _system database.

If the target databases do not exist yet on the backup server, it is possible to create them on the fly using the option --create-database true . Additionally, to restore system collections, arangorestore needs to be given the option --include-system-collections true .

That means, if your databases are really named "collection" and "collection2", your restore commands should look as follows:

arangorestore --input-directory "/tmp/dump/_system/" --server.database "_system" --include-system-collections true --create-database true
arangorestore --input-directory "/tmp/dump/collection/" --server.database "collection" --include-system-collections true --create-database true
arangorestore --input-directory "/tmp/dump/collection2/" --server.database "collection2" --include-system-collections true --create-database true

Please also note that with ArangoDB 3.5 there is an option --all-databases for both arangodump and arangorestore, which should greatly simplify the backup and restore process.

To take dump from remote server or local server execute the command

arangodump --server.endpoint tcp://ip_address:8529 --server.username test --server.password test --server.database dev --output-directory "dump" 

To restore from dump execute the below command

arangorestore --server.endpoint tcp://ip_address:8529 --server.username test --server.password test --server.database dev --input-directory "dump"
