metadata creation failed during backups

[shrief mohsen]

Dear All,

i have a new cpanel shared server version v84.0.9 i have several accounts that every day i take a backup for all these accounts on a directory called /backup when i mounted this directory path on a qnap disc it gives me this error every time "Some of the metadata database(s) appear corrupt". Scheduling a rebuild when i search for the error i found that some accounts has a problem with the metadata creation and it says in the log file database lockup is there a way to fix this error if not i want to ask if this error could affect the backup that has been taken for the cpanel accounts or not

Thanks & best regards

Hello,


The issue is that qnap NAS systems use CIFS which is unsupported. This is detailed in our documentation here: Backup Configuration - Version 84 Documentation - cPanel Documentation

• We strongly recommend that you do not perform backups to remote filesystems (for example, NFS, CIFS, smbfs, or other types of network drive systems). While you can back up directly to a remote filesystem, cPanel & WHM does not support this configuration. We strongly recommend that you work with a qualified system administrator to manage this custom backup path and avoid potential risks.

While the configuration is possible it isn't something we provide support for and our ability to assist with issues in relation to this is limited. We do have a kb article on how to address some permissions related issues with CIFS but I'm not certain that'd be related to the metadata issue you're having: How to Resolve CIFS-mounted Backup Drive Permissions Errors - cPanel Knowledge Base - cPanel Documentation

To further investigate, I'd suggest enlisting the assistance of a qualified system administrator. If you don't have one you might find one here: System Administration Services

Thanks!

@cPanelLauren is it ok to use iscsi for mounting backup instead

 

[cPanelLauren]

Hello,

iSCSI is a transport layer protocol which enables transport to a storage target, it is not a type of filesystem. Typically iSCSI is utilized with NAS and SAN systems, neither of which are supported by cPanel/WHM
