The All-in-One WP Migration plugin uses Backblaze B2 API to communicate with your account and store your backups. If there is an error communicating with your Backblaze B2 drive and the files that are stored in it, you might get one of these errors.
Backblaze B2 sets a per-user quota for each user to make sure that the resources available are shared fairly. If you have many other applications or systems connected to your B2 account you may encounter issues.
Configuring WordPress backups with Backblaze Log into your WordPress backend. In the Plugin area, update XCloner to the latest version. Locate the Site Backup item in the admin menu at the left and select Storage Locations Backblaze B2 Storage. Enter the keyID, applicationKey and bucket details. Backblaze encrypts all your files with the standard AES 128-bit, which is generally uncrackable. It is estimated that it would take a supercomputer several billion years to break it. Besides that, any would-be eavesdropper are kept at bay with file encryption being done. Backblaze Account Id Backblaze Application Key Backblaze Bucket Name Backblaze Cleanup (days) These are the only options for Backblaze. There is no field for the Bucket ID (which is not the same as a Bucket Name). And yes, I’ve tried putting it in as the Bucket Name which doesn’t work.
What can you do about it?
If the All-in-One WP Migration plugin cannot connect to your B2 drive, please sign out from your account and sign in again in the Backblaze B2 Settings page of the plugin on your WordPress Console.
Ensure that there are no other applications using your B2 drive at the same time as the All-in-One WP Migration extension. If you have other 3rd party applications or other services that are connected to your Backblaze B2 drive, consider stopping or uninstalling them. If you share large numbers of documents with other people or the public, consider an alternative solution to Backblaze B2.

Here is a complete list of cURL error codes:
CURLE_OK (0)
All fine. Proceed as usual.
CURLE_UNSUPPORTED_PROTOCOL (1)
The URL you passed to libcurl used a protocol that this libcurl does not support. The support might be a compile-time option that you didn’t use, it can be a misspelled protocol string or just a protocol libcurl has no code for.
CURLE_FAILED_INIT (2)
Very early initialization code failed. This is likely to be an internal error or problem, or a resource problem where something fundamental couldn’t get done at init time.
CURLE_URL_MALFORMAT (3)
The URL was not properly formatted.
CURLE_NOT_BUILT_IN (4)
A requested feature, protocol or option was not found built-in in this libcurl due to a build-time decision. This means that a feature or option was not enabled or explicitly disabled when libcurl was built and in order to get it to function you have to get a rebuilt libcurl.
CURLE_COULDNT_RESOLVE_PROXY (5)
Couldn’t resolve proxy. The given proxy host could not be resolved.
CURLE_COULDNT_RESOLVE_HOST (6)
Couldn’t resolve host. The given remote host was not resolved.
CURLE_COULDNT_CONNECT (7)
Failed to connect() to host or proxy.
CURLE_FTP_WEIRD_SERVER_REPLY (8)
The server sent data libcurl couldn’t parse. This error code is used for more than just FTP and is aliased as CURLE_WEIRD_SERVER_REPLY since 7.51.0.
CURLE_REMOTE_ACCESS_DENIED (9)
We were denied access to the resource given in the URL. For FTP, this occurs while trying to change to the remote directory.
CURLE_FTP_ACCEPT_FAILED (10)
While waiting for the server to connect back when an active FTP session is used, an error code was sent over the control connection or similar.
CURLE_FTP_WEIRD_PASS_REPLY (11)
After having sent the FTP password to the server, libcurl expects a proper reply. This error code indicates that an unexpected code was returned.
CURLE_FTP_ACCEPT_TIMEOUT (12)
During an active FTP session, while waiting for the server to connect, the CURLOPT_ACCEPTTIMEOUT_MS (or the internal default) timeout expired.
CURLE_FTP_WEIRD_PASV_REPLY (13)
libcurl failed to get a sensible result back from the server as a response to either a PASV or a EPSV command. The server is flawed.
CURLE_FTP_WEIRD_227_FORMAT (14)
FTP servers return a 227-line as a response to a PASV command. If libcurl fails to parse that line, this return code is passed back.
CURLE_FTP_CANT_GET_HOST (15)
An internal failure to lookup the host used for the new connection.
CURLE_HTTP2 (16)
A problem was detected in the HTTP2 framing layer. This is somewhat generic and can be one out of several problems, see the error buffer for details.
CURLE_FTP_COULDNT_SET_TYPE (17)
A problem was detected in the HTTP2 framing layer. This is somewhat generic and can be one out of several problems, see the error buffer for details.
CURLE_PARTIAL_FILE (18)
Received an error when trying to set the transfer mode to binary or ASCII.
CURLE_FTP_COULDNT_RETR_FILE (19)
This was either a weird reply to a ‘RETR’ command or a zero byte transfer complete.
CURLE_QUOTE_ERROR (21)
When sending custom “QUOTE” commands to the remote server, one of the commands returned an error code that was 400 or higher (for FTP) or otherwise indicated unsuccessful completion of the command.
CURLE_HTTP_RETURNED_ERROR (22)
This is returned if CURLOPT_FAILONERROR is set TRUE and the HTTP server returns an error code that is >= 400.
CURLE_WRITE_ERROR (23)
An error occurred when writing received data to a local file, or an error was returned to libcurl from a write callback.
CURLE_UPLOAD_FAILED (25)
Failed to start the upload. For FTP, the server typically denied the STOR command. The error buffer usually contains the server’s explanation for this.
CURLE_READ_ERROR (26)
There was a problem reading a local file or an error returned by the read callback.
CURLE_OUT_OF_MEMORY (27)
A memory allocation request failed. The mooch anthony scaramucci twitter. This is serious badness and things are severely screwed up if this ever occurs.
CURLE_OPERATION_TIMEDOUT (28)
Operation timeout. The specified time-out period was reached according to the conditions.
CURLE_FTP_PORT_FAILED (30)
The FTP PORT command returned an error. This mostly happens when you haven’t specified a good enough address for libcurl to use. See CURLOPT_FTPPORT.

he FTP REST command returned an error. This should never happen if the server is sane.
CURLE_RANGE_ERROR (33)
The server does not support or accept range requests.
CURLE_HTTP_POST_ERROR (34)
This is an odd error that mainly occurs due to internal confusion.
CURLE_SSL_CONNECT_ERROR (35)
A problem occurred somewhere in the SSL/TLS handshake. You really want the error buffer and read the message there as it pinpoints the problem slightly more. Could be certificates (file formats, paths, permissions), passwords, and others.
CURLE_BAD_DOWNLOAD_RESUME (36)
The download could not be resumed because the specified offset was out of the file boundary.
CURLE_FILE_COULDNT_READ_FILE (37)
A file is given with FILE:// couldn’t be opened. Most likely because the file path doesn’t identify an existing file. Did you check file permissions?

CURLE_INTERFACE_FAILED (45)
Interface error. A specified outgoing interface could not be used. Set which interface to use for outgoing connections’ source IP address with CURLOPT_INTERFACE.

Too many redirects. When following redirects, libcurl hit the maximum amount. Set your limit with CURLOPT_MAXREDIRS.
CURLE_UNKNOWN_OPTION (48)
An option passed to libcurl is not recognized/known. Refer to the appropriate documentation. This is most likely a problem in the program that uses libcurl. The error buffer might contain more specific information about which exact option it concerns.
CURLE_TELNET_OPTION_SYNTAX (49)
A telnet option string was Illegally formatted.
CURLE_GOT_NOTHING (52)

This second post is to clarify questions I had about some of the cloud based backup solutions. I haven’t tried out Jungle Disk, since the pay as you use storage costs would be too expensive for me. Also with Jungle Disk you would need to pay for the product and the storage costs. This would be expensive for me and so haven’t investigated the service further.
So for me personally it has come down to either Mozy or Backblaze.
Mozy
- User can customise the backup sets.
- Mozy account can be used to backup more than one computer
- If you supply a personal encryption key, the contents of your files are encrypted, but you can still view the file names from the web interface. I like using my own encryption key, but having to download a decryption utility means that I can’t easily get my data on another machine.
Backblaze
- I like that if you supply your personal encryption key you don’t have to use a decryption tool to retrieve your data. This makes it easy to get your data from another machine.
Conclusion
I have used both products and can’t really make up mind on which one I like better. Both products have their salient features. I’ll update this post when I finally decide which product I want to go with.
