Ubuntu Manpage: weresync - clone linux drives incrementally

NAME

       weresync - clone linux drives incrementally

       weresync-gui - GUI interface for the weresync program.

SYNOPSIS

       weresync [ options ] [-g ROOT_PARTITION] [-B BOOT_PARTITION]
              [-E EFI_PARTITION] [-L BOOTLOADER] [-l LVM_SOURCE [LVM_TARGET]] source target

       weresync-gui

DESCRIPTION

       WereSync  clones  linux drives incrementally producing a bootable clone. Clones produced by WereSync will
       have different UUIDs than the original drive, but WereSync will update the fstab and bootloader to  allow
       the clone to properly boot. Clones can be created with one command or one button click, using weresync or
       weresync-gui respectively.

OPTIONS

The weresync-gui command takes no arguments. These arguments apply to the weresync command.

--h, --help
Displays help message.

-C, --check-and-partition
Checks if all partitions are large enough and formatted correctly to allow drive to be copied. If
the partitions are not valid, the target drive will be re-partitioned and reformatted. If unset,
no checking occurs.

-s, --source-mask MASK
A string to be passed to format() that will produce a partition identifier (/dev/sda1 or such) of
the source drive when passed two arguments: the identifier ("/dev/sda") and a partition number in
that order. Defaults to "{0}{1}"

-t, --target-mask MASK
A string to be passed to format() that will produce a partition identifier (/dev/sda1 or such) of
the source drive when passed two arguments: the identifier ("/dev/sda") and a partition number in
that order. Defaults to "{0}{1}".

-e, --excluded-partitions LIST
A list of comma separated partition numbers that should not be searched or copied at any time.
These partitions will still be formatted if -C is passed. Defaults to empty.

-b, --break-on-error
If passed the program will halt if there are any errors copying. This flag is not recommended
because it will halt even if encountering a normal issue, like a swap partition.

-g, --root-partition PART_NUM
The partition mounted on /. It is recommended to pass this always, but WereSync will attempt to
find the main partition even if it is not passed.

-B, --boot-partition PART_NUM
The partition that should be mounted on /boot of the grub_partition. If you have a separate boot
partition, you must use this flag.

-E, --efi-partition PART_NUM
The partition that should be mounted on /boot/efi of the grub_partition. If passed this will
create the /boot/efi folder if it does not exist and pass it to grub. Required if you have an EFI
partition.

-m, --source-mount DIR
The directory to mount partitions from the source drive on. Cannot be the same as --target-mount.
If unset, WereSync generates a randomly named directory in the /tmp dir.

-M, --target-mount DIR
The directory to mount partitions from the target drive on. Cannot be the same as --source-mount.
If unset, WereSync generates a randomly named directory in the /tmp dir.

-r, --rsync-args RSYNC_ARGS
The arguments to be passed to the rsync instance used to copy files. Defaults to "-aAXxH --delete"

-l, --lvm SOURCE [TARGET]
This argument expects either one or two arguments specifying the logical volume groups to copy
from and to, respectively. If no target VG is passed, WereSync will use the VG SOURCE-copy. If the
target does not exist, WereSync will create it.

-L, --bootloader BOOTLOADER
The plugin to use to install the bootloader. Such plugins can be found at the bottom of the help
message. Defaults to using the "uuid_copy" plugin.

-v, --verbose
Makes WereSync increase output and include more minor details.

-d, --debug
Causes a huge amount of output, useful for debugging the program. Usually not needed for casual
use.

EXAMPLES

       To copy /dev/sda to /dev/sdb on a UEFI system use:

          sudo weresync -C -L grub2 -E 1 -g 2 /dev/sda /dev/sdb

       This  example  uses grub2 as the bootloader (for most other UEFI bootloaders use -L uuid_copy or omit the
       -L option all together) with the efi partition on /dev/sda1, and the root partition on /dev/sda2.

       Subsequent copies should omit the -C option, since it could cause weresync to repartition /dev/sdb again,
       thus deleting existing data and making weresync's incremental abilities useless.

       To copy /dev/sda to /dev/sdb on a BIOS/Legacy system use:

          sudo weresync -C -L grub2 -g 1 /dev/sda /dev/sdb

       This  example  uses grub2 as the bootloader (other bootloaders, such as syslinux, may be passed to the -L
       option) and has the root partition on /dev/sda1.  The omittance of the -E option signals to WereSync that
       this is not a a UEFI drive.

       As above, subsequent copies should be initiated without the -C option.

       The gui can simply be run with:

          sudo weresync-gui
