We have a couchbase server that somehow had a fresh installation and all our data that was there is lost. I had managed to take the backup of /opt/couchbase/var/lib/couchbase/data/ … Now when i try to copy the data back it is not showing the couchbase server.Any help is appreciated.

I am self-hosting a simple mondo database on Ubuntu 20.04 and the data I store is being deleted daily and I have no idea why
I am relatively new to MongoDB so if anyone has had something similar please let me know how I can fix this.
I'm migrating off of Parse to self hosted Parse server. In my staging environment, I need to initialize MongoDB so that it has all the collections of my production environment, but no data. Is there a way to do this without the data? I've attempted to clone my Parse DB and export the cloned DB's collections, but this has no effect on the collections visible to me through Parse Dashboard. Anyone know if this is possible?
Migrate your data, then use the parse dashboard and delete all the rows.
The database migration tool can be found in the Dashboard under App Settings → General → Migrate to external database.

I am currently working with couchbase server 1.8.1 an in a process of upgrading to 2.2 version.
We want to dump all the keys of couchbase 1.8.1 to a text file and then run on this file and copy all the data to the new couchbase 2.2.
The reason we chose to use this method instead of backup and restore is because our server do not respond well to backup and there is a risk of server failing.
Can you help me figure out how to create this dump file from couchbase bucket files?
In addition to what Dave posted, I recommend reading this blog post: http://blog.couchbase.com/Couchbase-rolling-upgrades
Also, there are some unique considerations when upgrading from 1.8.1 to 2.x, so make sure you read the documentation Dave linked to.
Note you can upgrade an existing cluster online (without having to manually copy data to a new 2.2 cluster) - see http://docs.couchbase.com/couchbase-manual-2.5/cb-install/#upgrading
We use this script: CouchbaseDump
It works and help us getting the keys from the sqlite files.
I use Netbeans to develop a project with JSF, JPA and Java database. I can make a back up online by right clicking the database connections under services and excuting CALL SYSCS_UTIL.SYSCS_BACKUP_DATABASE('c:/tem/2005-06-01') command. But how can I restore or create a database from that backup.
Several articles state that to use jdbc:derby:sample;restoreFrom=c:\mybackups\sample in the in the boot time connection URL. What is boot time connection? I tried to use it as the connection string in Netbeans new connection dialog, but that was not successful.
Please tell me how can I restore the backup.
There is a wealth of information about backing up and restoring Derby databases here: http://db.apache.org/derby/docs/10.9/adminguide/cadminhubbkup98797.html
If you're not comfortable using Derby outside of the Netbeans environment, start here: http://db.apache.org/derby/docs/10.9/getstart/
We want to restore the database that we have got from the client as backup in our development environment, we are unable to restore the database successfully, can any one help us to know the steps involved in this restore process? Thanks in Advance.
Vijay, if you plan to make a new database out of checkpoints (+journals) made on another (physical) server, then I must disappoint you - it is going to be a painful process. Follow these instructions http://docs.actian.com/ingres/10.0/migration-guide/1375-upgrading-using-upgradedb . The process is basically the same as upgradedb . However, if architecture of the development server is different (say backup has been made on a 32bit system, and development machine is, say POWER6-based) then it is impossible to make your development copy of the database using this method.
On top of all this, this method of restoring backups is not officially supported by Actian.
My recommendation is to use the 'unloaddb' tool on the production server, export the database in some directory, SCP that directory to your development server, and then use the generated 'copy.in' file to create the development database. NOTE: this is the way supported by Actian, and you may find more details on this page: http://docs.actian.com/ingres/10.0/migration-guide/1610-how-you-perform-an-upgrade-using-unloadreload . This is the preferred way of migrating databases across various platforms.
It really depends on how the database has been backed up and provided to you.
In Ingres there is a snapshot (called a checkpoint) that can be restored into a congruent environment, but that can be quite involved.
There is also output from copydb and unloaddb commands which can be reloaded into another database. Things to look out for here are a change in machine architecture or paths that may have been embedded into the scripts.
Do you know how the database was backed up?
