The filename where to dump the DB dbfilename mydump. The DB will be written inside this directory, with the filename specified above using the 'dbfilename' configuration directive. Also the Append Only File will be created inside this directory. Note that you must specify a directory here, not a file name. Improve this answer. Didier Spezia Didier Spezia Where is my mistake?
Evgeny I think maybe you made the same mistake I did and tried to restart the server. Make sure to STOP redis first, copy the dump. If you restart, redis will write to the file, overwriting your copied dump, and then imports the file it wrote to instead of the file you moved as the backup. We are successfully able to migrate db only when we first stopped redis server.
I think Ligemer comment is pretty important! Would be nice to have it in the answer which is spot on beside that little thing — mikey. This is an extremely poor and dangerous answer without mentioning anything about the appendonly setting in the redis.
So the server takes three different snapshots one after another of the data in the dump. I'm currently only using the RDB approach for maintaining persistence. Would really appreciate if I could get some clues for debugging and resolving this bug.
Additional information: OS: Ubuntu The text was updated successfully, but these errors were encountered:. Sorry, something went wrong. There were instances of the HDEL command being called but only because we have been calling that command in our application from time to time. The same problem happened to me two times today. The redis-server simply seems to restart without any request from me or my systems:. Computer Graphics. Software Engineering. Web Technology.

Rdbtools is written in Python, though there are similar projects in other languages. See FAQs for more information. Valid commands are: json, diff, justkeys, justkeyvals and protocol. Attempting to decode RDB data can lead to binary data curroption, this can be avoided by using the --escape raw option. Another option, is to use -e base64 for Base64 encoding of binary data.
Running with the -c memory generates a CSV report with the approximate memory used by that key. Memory usage includes the key, the value and any other overheads. Note that the memory usage is approximate. In general, the actual memory used will be slightly higher than what is reported.
