/tmp

is not a good location for the backup except as a temporary location before transferring it

off

box

The

/tmp

directory will not survive a reboot

The

/etc/config

directory is not a good

place either, as it will not survive

a restore.

Backup and restore should be done by the root user to ensure correct file permissions are set.

The config command is used to create a backup tarball:

config

e <Output File>

The tarball will be saved to the indicated location. It will cont

ain the contents of the

/etc/config/

directory in an uncompressed and unencrypted form.

Example nfs storage:

# mount

t nfs 192.168.0.2:/backups /mnt # config

e /mnt/

xxxxx

.config # umount/mnt/

Example transfer off

box via scp:

# config

e /tmp/

xxxxx

onfig

# scp /tmp/

xxxxx

.config 192.168.0.2:/backups

The config command is also used to restore a backup:

config

i <Input File>

This will extract the contents of the previously created backup to

/tmp

, and then synchroniz

the

/etc/config

directory wi

th the copy in

/tmp

One

possible

problem that can

occur

here is that there is not

enough room in

/tmp

to extract

files to.

The following command will temporarily increase the size of

/tmp

mount

t tmpfs

o remount,size=2048k tmpfs /var

If restoring

to either a new unit or one that has been factory defaulted, it is important to make

sure that the process generating SSH keys is either stopped or completed before restoring

configuration

If this is not done, then a mix of old and new keys may be put in

place.

As SSH uses these keys to avoid man

the

middle attacks, logging in may be disrupted.
