Mounting and Unmounting Containers

Mounting containers

In order to access to data stored in container you should mount it. Container is mounted by following command (you will be prompted for a password):

bctool mount [-t filesystem_type] [-m mode] [-u user] [-g group] [-r] container mount_point
or
bcmount [-t filesystem_type] [-m mode] [-u user] [-g group] [-r] container mount_point

where
`-t filesystem_type`	standard filesystem name, e.g. -t vfat
`container`	container filename
`mount_point`	the point where to container will be mounted
`-m mode`	set mountpoint access mode, e.g. -m 755
`-u user`	set mountpoint owner (can be used by root only), e.g. -u jukka
`-g group`	set mountpoint group (can be set by root only), e.g. -g bros
`-r`	mount container read-only

In following example container named secret_data with ext2 filesystem is mounted to /mnt/secrets mount point.

[foo@bar ]$ bctool mount -t ext2 secret_data /mnt/secrets Enter password: <password will not be displayed> [foo@bar ]$

Notes:

Mounted BestCrypt containers are not protected from deletion.
Container may be mounted onto its parent directory.
When mounting the hidden part of container filesystem type must be explicitly specified. Otherwise BestCrypt will try to guess the filesystem type from the main part of container.

Unmounting containers

BestCrypt for Linux offers two ways to unmount container:

conventional safe unmount
urgent or forced unmount

Warning: Forced unmount is a security enhancement intended for emergency use only. It does not take care of open files, unsaved data etc. and may lead to partial data loss

Container unmount command syntax follows:

bctool umount { mount_point | -A } [-f]
or
bcumount { mount_point | -A } [-f]

where
`mount_point`	the point where to container is mounted
`-A`	unmount all containers mounted by current user
`-f`	forced unmount; container will be unmounted regardless whether it is in use or not Warning: this option should be used for urgent unmount only, not for normal operation. All unsaved information in container will be lost when using `-f` option.

We unmount container previously mounted to /mnt/secrets.

[foo@bar ]$ bctool umount /mnt/secrets [foo@bar ]$
This example shows urgent unmount of all containers mounted by current user

[foo@bar ]$ bctool umount -f -A [foo@bar ]$

Notes:

BestCrypt containers are protected from unmounting by standard umount.
