Backup Data from Physical Server to Cloud ERPNext

I want to backup all my data from physical server to ERPNExt cloud.
Please kindly let me know how to do that?

It should be as simple as running the database backup on the physical server and asking the cloud administrator to restore it to your cloud instance.

I have done this many times between physical boxes and my own VPS servers on several different VPS providers.

Unless you have several years of data, the size of the compressed backup file is only a few hundred megabytes in size. I think my avers database backup for a year of data is about 2gb database compressed to about 210mb in a backup file. Just remember to get a backup with all the files in the /public/files and /private/files directories as well.
