The information in this Wiki Page applies to TANE, TRS19 and Trainz Plus. This guide will explain automatic and manual backups in Trainz.

Main Points:
	Trainz will automatically backup your current route and session while you work. You can set the number of backups created each day
	You can use Content Manager to manually create backups of routes, sessions and assets as often as you need
	Both the manual and automatic backups can be restored to Trainz by Content Manager

Automatic Backups vs Manual Backups

	Automatic Backups	Manual Backups
Pros	set and forget - no need to remember to perform the backups backups are stored in a set location automatic restore after a crash	you control where the backups are stored you control the backup file names any assets can be backed up, not just routes and sessions
Cons	identifying the exact backup file to restore may not be easy only routes and sessions can be backed up last 7 backups only are kept	you have to remember to perform the backup you have to remember where you stored the backups manual restore after a crash

Automatic Backups

Creating Automatic Backups

In Summary:
	Only a set number of backups are created each day
	Only 7 days of backups are kept

This is a Set and Forget operation. You simply tell Trainz how many backups you want created each day and the program takes care of the rest.

Steps:

To set the number of backups, select Trainz Settings from the Launcher and then click the Dev tab.
One data entry box in this tab will be named Daily backups to keep and it will have a default value of 7. Set it to the number of backups you want each day.

		If you are working on developing a new route or session then 7 daily backups could be a suitable number.
		If you are making minor changes to existing routes or sessions then 3 or 4 daily backups could be a suitable number.
		If you are not working on any routes or sessions then 0 daily backups could be a suitable number - but remember to reset this when you do need the automatic backups again.

Warning:
	If you set 0 daily backups then there will be no option to restore your route/session to the latest automatic backup after a crash

Large Number of Daily Backups	Small Number of Daily Backups
more backup storage space is needed shorter time between backups so less work can be lost	less backup storage space is needed longer time between backups so more work can be lost

Only the last 7 days of backups are kept and this number cannot be changed.

Restoring Automatic Backups

The automatic backups are stored in a backup folder in your Trainz local data folder. The location of this folder is held in your Launcher - Trainz Settings - Install tab.

	Step 1: Open the Backups Folder using Windows File Explorer, open your local data folder and then open the backups folder. the backups that have been created during the past week will be listed by their dates using the YY-MM-DD date format.

Step 2: Identify the Backup to Restore

open the backup folder for the date that you want. A list of backup files and folders created that day will be shown.

if you know the time of the backup then sort the entries by date. Some entries, as shown above, have randomised names and will have to be sorted by date.
if you know the kuid of the backup (it will be the same as used by the route/session) then sort the entries by name.

	Step 3: Restore the Backup To Trainz open Content Manager drag and drop the selected backup folder from Windows File Explorer into Content Manager the item will be shown in Content Manager as Open for Edit. Select the item and Submit it.

More details, including tips on troubleshooting, can be found in the Trainz Knowledge Base at Restoring Backups

Manual Backups

In Summary:
	You control the number and frequency of backups
	You control the backup location and filenames
	Assets, not just routes and sessions can be backed up

Creating Manual Backups

	Manual backups are stored as .CDP files
	Many assets can be stored in a single .CDP file

Steps:

open Content Manager and use a search filter to identify the assets to be backed up. Some examples:-


		to show all assets that have been altered today.

		to show all installed routes that are yours.

highlight the asset or assets (more than one asset can be included in each backup file).
right mouse click on one of the highlighted assets and select Export to CDP.

Export to CDP

select a drive, folder and enter a backup filename.

Restoring Manual Backups

Simply drag and drop the backup CDP file or files into Content Manager

Steps:

open Content Manager
open Windows File Explorer and locate the backup folder
highlight the .CDP file or files to be restored
drag and drop the file or files from Windows File Explorer into Content Manager
if the assets being restored are already installed in Content Manager then their status will be Open for Edit. Submit the assets.

Restore from backup

Backup Plan Basics

If you are using a manual backup method then devise a simple backup plan and stick to it

The most important parts of any backup plan are:-

make regular backups - how often will depend on the complexity of the project
keep duplicate sets of backups including on offline storage
keep previous backup sets, not just the latest ones - how many past sets you will want to keep will depend on factors such as available storage
have a simple but consistent file naming system to be able to quickly identify the backup you need to restore lost work

Sample Backup Plan:

on a drive that is always attached to your system create a Project Backups folder
in this folder create another folder named Today

Online Project Backups folder

use this folder to store your regular backups for today. For example, when you take a break and exit from Surveyor, start Content Manager and backup the current project (e.g. a route, a session or both) to the Today folder

Todays Backups folder

name each backup using the name of the project and the time as shown in the example above

Why Keep Separate Time Backups For The Same Day?

Suppose that after your first backup of the day, at say 07:52, you decided to make some significant changes to your route. The later backups made at 12:30 and 14:10 included this change. By 17:00 you decide that this major change is not working and you need to return the route to its starting state. If your only backup was the last one you had made at 14:10 then you could not restore the route to its starting state.

at the end of each day copy the Today folder to an external drive such as a USB or a detachable SSD into a folder also called Project Backups
rename the Today folder on the external drive to a format that identifies the date of the backups it contains (using the yyyy-mm-dd format) as shown below

Offline Project Backups folder

copy this renamed folder to a second external detachable drive (if you have one) in its Project Backups folder
when starting work the next day, delete the contents of the Today folder on your main drive and make the first backup of the day using the project assets in their initial state for the day

How Long Should You Keep The Daily Backups?

The ideal answer is until after the project has been finished but in reality it will depend on your available storage space. The use of a large capacity external storage device would be the ideal solution for a complex project that may involve months or even years of work and hundreds or thousands of backup files. Once the project has been completed then these files may be deleted.

If a decision is later made to restart work on the project then it would be considered to be a brand new project with a set of starting assets (the route and sessions) and the backup procedure can be restarted from that point.

Backing Up and Restoring Picklists

Picklists have to be exported and imported as text files

Picklists cannot be backed up manually using .CDP files. They must be exported as text files.

Detailed instructions on backing up and restoring Picklists as text files can be found on the Trainz Wiki Page at:-

How to Backup a Picklist

Restarting After a Crash

If you experience a system crash, a power failure or a CTD (Crash To Desktop) while using Trainz and the automatic backups are on (not set to 0 daily backups) then there is a chance that Trainz has performed at least one automatic backup before the crash. In this case when you restart Trainz and reload the route/session you will be informed that changes to the original route or session have been detected and you will be given the option to Revert Changes or Use Changes .

If you select Revert Changes then the last manually saved version of the route/session will be loaded into Trainz and any changes made since the last manual save will be ignored.

If you select Use Changes then any automatically saved changes to the last manually saved version of the route/session will also be loaded into Trainz.
