Manage data store backups

You need backups to recover your data in the event of a disaster such as data corruption or data store failure. If you create backups of your data store and place them in a safe location, you can set up a new ArcGIS Data Store, access your backup, and restore the data used by your hosted layers if for any reason your data store crashes and cannot be restarted.

If you have only a relational data store, ArcGIS Data Store is configured to automatically create backups of your data. By default, the data store creates backups of feature layer data automatically in c:\arcgisdatastore\backups. That means backup files are stored on the same machine as the relational data store. If the data store or primary machine fails, you can't access the backup files and, therefore, cannot restore your hosted feature layer data. For that reason, you should store your backups in a location other than the default.

The following diagram shows a relational data store made up of one computer (the primary machine) for storing your data, plus a network drive to store backup files. Storing the backup files on a machine separate from the data store protects you from losing the backup files if the machine running the data store fails.

ArcGIS Data Store with one machine and a mapped network drive for storing backup files


Be aware that backup files only contain the data used by your portal's hosted feature layers. Backup files do not maintain a backup of scene layer data or caches, spatiotemporal big data stores, the ArcGIS Server site, or your portal. Rather, backups help you recover feature layer data lost if the data store's primary machine fails. If you want your hosted feature layers to work, even if the primary machine fails, set up a standby machine.

In addition to defining a different backup directory, you can also control how often full backups are created and how long backup files are retained.

If needed, you can use the backupdatastore utility to manually create a backup of the feature layer data.

If you need to move your data store's hosted feature layer data to a newer release of ArcGIS Data Store, or you want to restore the data to an installation of ArcGIS Data Store on a machine with a different operating system, export the data store, and import it to the other ArcGIS Data Store.

If you want to make backup copies of hosted scene layer tile caches along with hosted feature layer data, you can export the data store using the exportmanageddb utility installed with ArcGIS Data Store or the webgisdr tool that is installed with Portal for ArcGIS.

Define a backup location for relational data stores

Backups let you recover your data if a disaster occurs, such as when your server fails or flood waters destroy your server. If your backup is on the server that is destroyed in a flood, you cannot recover your data. Therefore, you need to store your backup files on a different server than your relational data store.

If you did not specify a domain ArcGIS Data Store account when you installed or upgraded ArcGIS Data Store, set the data store service to run using a domain account now, and grant that account read and write access to a shared network directory. Next, use the changebackuplocation utility to move your data store backup files to the shared directory on a different machine. Ensure there is enough storage space to hold all the files that are included in a relational data store backup. The number of files and size of the files will vary depending on your data, your backup schedule, and the number of days you retain backups. Be sure to monitor the size of the backup directory and adjust these settings as needed.

The changebackuplocation utility is installed in the <ArcGIS Data Store installation directory>\datastore\tools directory.

The syntax to run the changebackuplocation utility is as follows:

changebackuplocation <new directory path> --is-shared-folder <true|false> --keep-old-backups <true|false>

For example, type the following to create backup files in a shared directory named ds_backup on a computer named sysshare and opt to keep existing backup files:

changebackuplocation \\sysshare\ds_backups --is-shared-folder true --keep-old-backups true

You are going to change the backup location of the data store. Existing backups will be copied to the new location and it could take a few moments.
Please do not interrupt the process once it has started.

Do you want to continue (Yes or No)? Yes


If your remote backup directory goes offline for more than a few minutes, perform a full manual backup of the data store as soon as the shared backup location is available.

Change backup frequency for relational data stores

By default, the data store creates a full backup of feature layers every four days and incremental backups either when the log files are full or every five minutes, whichever comes first. (Log files allow you to recover to a specific point in time.) The database controls incremental backup creation, but you can change how often the data store creates a full backup by running the updatebackupschedule utility. If your users will be publishing and editing large numbers of hosted feature layers, you should increase the frequency with which full data store backups are created.

Note that your backup location must have enough room to store all the backup files. Backup size varies depending on the amount of data you have but, if you use default backup settings, backups will contain two full backups and seven days of incremental backup files. The size of these files depends on the amount and size of your data.

If you decide to create backups manually and want to disable automatic backups, set the backup frequency to 0. Be aware that ArcGIS Data Store will not create full or incremental backups if you disable automatic backups.

The updatebackupschedule utility is installed in the <ArcGIS Data Store installation directory>\datastore\tools directory.

  1. Open a command prompt using the Run As Administrator option.
  2. Run the updatebackupschedule utility to specify the backup frequencies you require.

    The syntax to run the utility is as follows:

    updatebackupschedule --starttime <local server time> --frequency <number of days>

    For example, type the following to schedule full backups at 3:00 a.m. (local server time) every day:

    updatebackupschedule --starttime 03:00:00 --frequency 1

Change how long relational data store backup files are retained

The backup directory retains backup files for seven days by default. That means if you keep the default backup frequency (every four days) and retention schedules (seven days), the backup directory will contain two full backups and seven days of incremental backup files. The size of these files depends on the amount and size of your data. The machine that stores your backups must have enough disk space for all these files. If you increase the backup frequency, consider decreasing the retention period for the backup files. In the previous section, the backup frequency was increased to every day. To prevent your backup directory from becoming too large, decrease the backup file retention period.

The syntax to run the updatebackupretaindays utility is as follows:

updatebackupretaindays <number of days>

In the following example, backup file retention time is changed to four days:

updatebackupretaindays 4

Manually create a relational data store backup

You can use the backupdatastore utility to make a full backup of the feature layer data in your data store. You might manually create a full backup prior to making a large number of changes to the data store or prior to upgrading the data store. Or you might create a backup to preserve a copy of the data in a particular state, for example, at the end of the first phase of a project. The login with which you connect to the data store machine to run the backupdatastore utility must have read and write access to the data store backup location.

The syntax to run the backupdatastore utility is as follows:

backupdatastore <backup_name>

Provide a meaningful name for the file so you can find it when you want to restore the data. If you do not specify a name, the utility assigns a default name to the file. The default name is in the format datastorename-timestamp. For example, if your data store is named corpds and you create the backup on July 10, 2014 at 14:25:49:554 UTC, the backup file name is corpds-20140710142549554.

You will be asked to confirm that you want to create a backup. Type yes or y to proceed with backup creation.


If you want to script manual backups, include a flag to suppress the confirmation prompt, as in the following example:

backupdatastore --prompt no

In this example, the data store will generate the backup file name. This is necessary in a script to ensure a unique backup file name.

Delete manual backups

If you no longer need to keep a backup file you created using the backupdatastore utility (a manual backup), you can run the listbackups utility to get the name of the specific backup file, and then run the deletebackup utility to remove the unneeded file. For example, once you have upgraded your data store and confirmed all feature layers are performing as expected, you could delete the data store backup you created prior to upgrading.

In this example, the database preupgrade1104_bu is deleted.


Backup_Name                      Status           Backup_Time         Mode
phase1proj_bu                    BackupComplete   2014-03-08 14:12    manual
phase2proj_bu                    BackupComplete   2014-06-21 11:43    manual
preupgrade1104_bu                BackupComplete   2014-10-04 09:30    manual
ds_gdt1oomh-20141103160748082    BackupComplete   2014-11-01 03:00    scheduled

deletebackup preupgrade1104_bu
You are attempting to delete backup 'preupgrade1104_bu'. This operation is irreversible.

Do you wish to continue (Yes or No)?yes

Export ArcGIS Data Store relational and scene layer tile cache databases

When you use ArcGIS Data Store, it stores the data for hosted feature and scene layers, as well as the scene layers' tile caches. You can export hosted feature and scene layer data and the scene layer tile caches using the exportmanageddb utility. You would do this if you want to move the ArcGIS Data Store installation to a machine with a different operating system or to a different ArcGIS Data Store release. You would also do this so you have a backup of your scene layers and caches. Use the importmanageddb utility to restore the database to the new ArcGIS Data Store installation.


Alternatively, you can use the webgisdr tool installed with Portal for ArcGIS to create a backup that contains your relational and tile cache data stores. See Web GIS backups in the Portal for ArcGIS Administrator Guide for more information on using this tool.

For example, if ArcGIS Data Store is running on a Windows server, but your information technology department is switching to Linux servers, you can do the following to move the data store to the new server:

  1. Install ArcGIS Data Store on the Linux server, but do not proceed with configuring a data store.
  2. Export from the existing ArcGIS Data Store on the Windows server using the exportmanageddb utility. Export to a shared location that can be accessed by the new machine.

    In this example, the data store is exported to a directory named ds2move on a shared location, \\sharedbox\exports.

    exportmanageddb ds2move --destination \\sharedbox\exports

  3. Import the files to the new ArcGIS Data Store installation using the importmanageddb utility on the new machine. Specify --bound true so your ArcGIS Server site will use the data store in this new location, and existing hosted feature and scene layers will continue to work.

    In this example, the new data store's data directory is /usr/arcgis/datastore.

    importmanageddb ds2move --source-loc /net/sharedbox/exports/dbdump/ds2move --data-dir /usr/arcgis/datastore --server-admin siteadmin --server-password HeyeLee$ecur3 --bound true
