Which Directories Are Not Synchronized by Default During Incremental Synchronization on a Linux Server?
When incremental data synchronization is performed after full replication is complete on a Linux server, data will not be synchronized for the following directories related to host configurations:
/proc/*, /sys/*, /lost+found/*, /tmp/_MEI*, /var/lib/ntp/proc/*, /boot/*, /boot/efi/*, /etc/fstab, /etc/*, /etc/X11/*, /root/initrd_bak/*, /lib/modules/*, /boot/grub2/x86_64-efi/*, /boot/grub2/i386-pc/*
Reasons
After the first full migration of a Linux server, some parameter settings in the preceding directories on the target server are modified to make the target server compatible with Huawei Cloud and ensure that the target server can start properly. During incremental synchronization, to ensure that the parameter settings in these directories on the target server are not overwritten or modified by the source data, the data in these directories on the source server is not synchronized by default.
Important Notes
If there is service data in the preceding directories, you need to manually synchronize the incremental service data to the target server.
