Backing Up the User File System

1.Create a backup file. The specific commands used to back up the user file system depend on whether the firmware version is earlier or later than version V1.5.

Firmware versions earlier than V1.5 (not including V1.5)

#upramdisk

#backupfs /mnt/ramdisk/usrdisk

Firmware version V1.5 (and later versions)

First type the following command to enable the RAM disk:

#upramdisk

Next, use the file system backup utility provided by Moxa:

#backupuf /mnt/ramdisk/usrfs-backup

Alternatively, you may type the following command to back up the file system to the CF card:

#backupuf /mnt/hda/usrfs-backup

2.Once the file system is backed up, use FTP to transfer the file usrfs-backupto your PC.

Now backup the user root file system. Please wait. . .

Deploying the User File System to Additional UC-7420/7410 Units

For some applications, you may need to ghost one UC-7420/7410 user file system to other UC-7420/7410 units. The specific commands used to carry out this procedure depend on whether the firmware version is earlier or later than version V1.5.

Firmware versions earlier than V1.5 (not including V1.5)

Type the following commands to force the system to jump to the Mini File System:

#mv /etc/inittab /etc/inittab.bak #reboot –r now

#upramdisk

Use ftp to download the backup file of the user file system from the PC to the /mnt/ramdisk directory:

#bf /mnt/ramdisk/usrdisk #reboot –r now

Firmware version V1.5 (and later versions)
