1.Comodo Time Machine - Introduction

Comodo Time Machine (CTM) is a powerful system rollback utility that allows users to quickly restore their

computers to an earlier point in time. CTM 'snapshots' are a complete record of your entire system (including the

registry, critical operating system files and

user created documents).

As part of a layered security strategy, users can schedule automatic snapshots to be taken at regular intervals then roll

back to the last known working state in the event of virus attacks or crashes. It is also a recommended practice to take

snapshots of your computer before large installations or system maintenance like installing a Windows service pack,

security updates or new drivers. Software Developers and testers can easily restore test systems to the default

configuration after each deployment without the need to manually uninstall each application. Home users can even let the

kids run amok on the family PC for an afternoon and be safe in the knowledge that any damage can be instantly undone

and all files recovered.

Comodo Time Machine features an intuitive, friendly interface which offers quick and easy access to all functionality in the

application. Additionally, it also features a sub-console that can be accessed before Windows starts and a Quick Operation

console containing shortcuts to important and commonly executed tasks.

Key Features and Benefits:

• Easy to use - even beginners can quickly create system snapshots with a few mouse clicks

• Provides instant and comprehensive system recovery after virus or spyware infections

• Instantly reclaim your machine after devastating system crashes

• Rollback the changes to ALL your documents - not just changes to system files and the registry

• Boot-up console allows you to rollback even when your system will not boot to Windows

• Test new software and network configurations in the knowledge that you can quickly switch back if problems

Comodo

Time

Machine

User

Guide

Windows Server 2008 (32 and 64 bit. Except Windows Server 2008 Core)

Minimum Hardware Requirements

Intel Pentium III Processor or higher

128 MB RAM

Free Disk Space*

4 GB (minimum) / 10 GB (recommended)

* Free disk space is required for the creation of snapshots. These requirements apply to each 'bootable' drive upon which

Comodo Time Machine is installed (e.g. If you have a dual boot system then you have to install CTM on both drives. The 4

GB/10 GB space recommendations apply to both those drives.)

1.1.2. Important Installation and Usage Information

In order for Comodo Time Machine to function correctly, it MUST be installed on all operating systems on a

multi-boot system.

CTM writes its snapshots and internal data to free disk space. If this data gets overwritten then your snapshots may

become corrupted (and in certain cases your computer may even fail to boot properly.) To prevent programs from

overwriting this data, CTM assumes full control of all read/write processes on the protected operating system. If CTM is not

installed on the particular OS that you are booting to, then CTM does not have the required control to prevent the OS, users

or other programs from over-writing this essential data.

• If you have a dual or multi-boot system, install CTM on all operating systems that you plan to use (boot into). Do

not boot your system with an operating system that does not have CTM installed.

• Once CTM has been installed on all operating systems, you should not physically unplug/remove the protected

drives from the motherboard then operate your system. Neither should you re-arrange the channels/shots that

each drive is plugged into. Doing so will essentially 're-arrange' the configuration of your drives on which CTM

has based your snapshots and therefore render them invalid. If you wish to carry out system maintenance such

as this then we advise you to (i) copy or save all data that you need (ii) uninstall CTM from all drives (iii) carry out

the maintenance (iv) re-install CTM on all operating systems. This will mean CTM can begin creating snapshots

based on your new configuration.

• It is not possible to install a new operating system on protected drives after CTM has been installed. Again, if you

wish to install a new OS, we advise you first make sure you have saved all data then follow the uninstall/re-install

process outlined in the previous bullet.

• If the system is booted from removable media like CD or DVD or into an environment such as WinPE , then

please take care to ensure that you do not write any new data to protected drives.

• If you plan to re-size or adjust the size of a partition using 3rd party or Windows software, then make sure this is

done from an operating system that has CTM installed. Do not re-size a partition from an environment 'outside'

CTM control - such as WinPE, DOS or if you have booted from a DVD.

• Do not run another piece of software of the same functionality as Comodo Time Machine.

Note: It is OK to use Windows System Restore at the same time as CTM because that is a file-level restore system.

Step 7 - Installation on Multi-Boot Systems

Comodo TimeMachine User Guide |

Comodo

Time

Machine

User

Guide

Important. Comodo Time Machine must be installed on all bootable partitions that have an operating system. It is vital

that users boot into each OS and install CTM on each. Failure to do so can lead to corruption of CTM snapshots if you

choose to start an OS that does not have CTM installed (the OS will write to disk space required by CTM during boot).

For more information on this and to view other important considerations, please see the Important Installation and

Usage Information section of the System Requirements chapter.

If the setup wizard detects that your system has multiple operating systems then it allows you to specify an installation

option that corresponds with your current situation. If your system is not a multi-boot computer, this step will be skipped and

the process moves to step 8.

• This is a single boot computer. - If your computer has a single operating system installed, select this option

and click 'Next'

• This is a multi-boot computer and I have not installed the products to the others yet - Select this option if

your computer has multiple operating systems installed and click 'Next'. After installation on the present OS is

complete you should boot your computer into the other operating systems (one by one) and install Time Machine

in each of the operating systems. The installation process moves to step 11 on selecting this option.

• On installing Comodo Time Machine on the final operating system, select 'This is a multi-boot computer and

this is the last operating system I am installing the product'. The installation process moves to step 8.

Click 'Next' to continue.

Step 8 - Select Partitions to be Protected

The next step is to specify the drive partitions to be protected by Comodo Time Machine.

Comodo TimeMachine User Guide |

Comodo

Time

Machine

User

Guide

To select the partition(s) select the check box(es) beside the drive letter(s) and click 'Next'.

Important Note: You cannot change the protection status of the drive partition(s) and cannot unplug/remove the protected

drives and change the SATA/PATA/IDE/SCSI slots of the motherboard through which the disk drive is connected.

Step 9 - Moving Folders to Unprotected Partition

The next step allows you to move selected user folders from the protected partition you selected in step 8 to an

unprotected partition. Doing so, will:

• Save the disk space in the protected partition;

• The user data stored before the installation of Comodo Time Machine can be easily recovered if you are

uninstalling the application and restoring the system to your baseline snapshot during uninstallation.

Note: This step appears only if at least one unprotected partition is left in your system while selecting the partitions to be

protected in step 8. If you chose to protect all the partitions, this step will be skipped and the installation will proceed to

step 10.

Comodo TimeMachine User Guide |

Comodo

Time

Machine

User

This is optional. If you wish to move the User Folders to an unprotected partition;

• Select the checkbox 'Move the following folder to the unprotected partition' and select the unprotected partition

from the drop-down box beside.

• Choose the Folders to be moved by selecting the checkboxes beside the folder names in the list. If you want to

move all the folders, select the checkbox 'Select all' below the list.

Important Note: You cannot revert the folders to the protected partition once you have moved the folders.

Click 'Next' to continue.

Step 10 - Turn Off System Restore

The next step allows you to switch off the Windows System Restore function.

As the Comodo Time Machine application will be responsible for taking the snapshots of your system at various time points

after its installation, you do not need the Windows Operating System to create snapshots to help you to restore your

system to a previous point of time. Turning off Windows System Restore saves enormous disk space without compromising

your system's safety and performance.

3.2.3. Mounting a Snapshot as a Virtual Drive on Your Computer

Mounting a snapshot as a virtual drive provides you an easy way to access the files/folders in a selected

snapshot, without the requirement of rolling back your system to the selected snapshot. You can also copy the

files which were lost due to rolling your system to a different snapshot, from the mounted snapshot to the current

system, and synchronize files between different mounted snapshots.

To mount a snapshot as a virtual drive

1. Right click on the snapshot.

2. Select 'Mount Snapshot' from the context sensitive menu. The 'Mount mode select' dialog will appear.

3. Select the mode in which you want the snapshot to be mounted in your computer.

Guide

1 - Mount with read-only access (Recommended) - Mounts the snapshot as a read-only drive. You can browse

your files and folders in the snapshot without rolling back to the snapshot and even copy them to your current

system.

2 - Mount with full access - Mounts the snapshot as a virtual drive with full read and write access. You can

browse and even edit/delete the files in the snapshot without rolling back to the snapshot and copy them to your

current system. When you rollback your system to the same snapshot, the changes that you made in the virtual

drive will be reflected. Comodo TimeMachine will create a snapshot on unmounting the disk to save all the

changes.

4. Click 'OK'. The mounting progress will be indicated.

The completion of mounting will be indicated by a pop up at the bottom right of the screen. Clicking the text in the pop up

will open the mounted drive in Windows Explorer. The snapshot will be mounted as a virtual drive with an unsued drive

letter (typically drive Z, X, Y etc) and can be accessed using Windows Explorer as a normal drive. If you have used all the

drive letters from C to Z, you can opt for mounting the drive in a specified NTFS directory by selecting the option Mount

snapshot into NTFS directory from the Settings > Program Settings interface. Click here for more details.

You can access the mounted snapshot by two ways:

1. Through the system tray icon - Double click on the system tray icon.

The mounted drive will be opened in Windows Explorer.

mounted drive.

Note: You can mount only one snapshot at a time as a virtual drive. If you want to mount a different snapshot , remove

the existing virtual drive and mount the snapshot you wish.

To remove the virtual drive, right click on the snapshot mounted as virtual drive and select 'Dismount' from the context

sensitive menu or right click on the virtual drive icon in the system tray and select 'Dismount'.

4.Restoring Your System

Once you have successfully created a system snapshot, you can roll your system back to it anytime you want.

You may want to do this to reinstate a previous 'working' state after you encounter a virus attack, problems due

to newly installed software or data corruption.

Another use of this functionality would be to reset a model system environment when testing software or hardware. Any

changes, damage or data corruption that occurred after that snapshot will be discarded and your system will be reverted to

the system configuration at the time of taking the selected snapshot.

Tip: If you encounter a system crash and Windows does not start, you can enter the sub console of Comodo Time

Machine, which is accessible immediately after you switch on your system and roll back your system to a last known

healthy snapshot. Click here for more details.

To access the Restore System interface, click Restore System tab from the main interface. The Restore System interface

will display a list of all the previously taken snapshots in chronological order.

5.Scheduled Tasks

Comodo Time Machine's flexible scheduler allows you to take automatic system snapshots at intervals of your

choice and/or immediately before running selected executables. Once set, the scheduler will continue to take

snapshots at the time or event you specified without any further intervention on your behalf. If you are

unfortunate enough to encounter any system failures, virus attacks or data corruption then you can easily

rollback your system to the last known working configuration.

Obviously, the more frequently that you take scheduled snapshots, the more likely that the latest snapshot will contain all

your recent documents and system changes. Users can also schedule CTM to run automatic system restore tasks. A

scheduled restoration is useful if you want a system to rollback to a specific configuration at the end of a certain time period

so that you (or the users of the target machines) will always begin working with an 'ideal' configuration (for example,

computers in Internet cafes and public libraries).

To access the Scheduled Tasks interface, click the 'Scheduled Tasks' tab from the main interface. From this interface you

can:

6.Recovering Individual Files/Folders

The 'Recover Files' feature allows you to locate and restore individual files and folders from any snapshot. This

is especially useful if files are accidentally lost, important data is corrupted or simply to find an older version of a

particular file. The ability to recover files in this way avoids the need for a full rollback and provides users with

the flexibility to access data and files across multiple points in time.

Tip: You can also rollback (or synchronize) the current version of a file/folder to an older version by right clicking on the

file/folder from Windows Explorer. Click here for more details.

To recover a lost file/folder

1. Click 'Recover Files' tab from the main interface. The Recover Files interface will open.

• Enter the name of the file/folder you want to recover in full or in part in the 'All or part of the file name' text box.

7.Resetting the Baseline Snapshot

The 'baseline' is the snapshot taken at the time you first installed Comodo Time Machine. This serves

as the foundation snapshot for all subsequent snapshots. It is locked by default and cannot be deleted

from the View Snapshots interface. You may want to reset this baseline after a major update like

Comodo TimeMachine User Guide |

Comodo

Time

Machine

User

Guide

installing a Windows Service Pack or after implementing system configuration or software changes that

you regard as highly important.

By resetting the baseline snapshot you will:

• Delete the old baseline snapshot and all child snapshots that were derived from it;

• Set the current state of your system as the new baseline - thus creating a reference snapshot for all subsequent

snapshots.

Comodo recommends that users only reset the baseline once they are satisfied that all installed programs and devices are

working correctly and that there are no problems with the current system configuration.

To begin the baseline reset process, click the 'Reset Baseline' button at the upper right of the interface:

• In order to remove the previous baseline and the previous snapshots, your computer needs to be restarted. Save

all unsaved data in other open applications, close all the other applications and click Reboot to restart your

computer. A confirmation dialog will appear.

• Click 'Yes'.

On restarting, the current state of your computer will be set as the new baseline and this will stand as the foundation for the

other snapshots taken in future.

Tip: You can also reset the Baseline Snapshot from the Windows Command Line interface. Click here for more details.
Note: Since all the other snapshots (both locked and unlocked) from the previous baseline will be deleted permanently, 
you will not be able to recover any files/folders from them after resetting the baseline. Use the Recover Files option or 
Mounting the Snapshot option to synchronize the files between the previous snapshots and the current system.
