5 | Backups are simply a copied snapshot of the entire [wiki:TracEnvironment project environment] directory, including the database. Backups can be created using the `hotcopy` command in [wiki:TracAdmin trac-admin]. |
---|
6 | |
---|
7 | '''Note''': Trac uses the `hotcopy` nomenclature to match that of [http://subversion.tigris.org/ Subversion], to make it easier to remember when managing both Trac and Subversion servers. |

9 | == Creating a Backup |
---|
10 | |
---|
11 | To create a backup of a live TracEnvironment simply run: |
---|
12 | {{{#!sh |
---|
13 | $ trac-admin /path/to/projenv hotcopy /path/to/backupdir |
---|
14 | }}} |
---|
15 | |
---|
16 | [wiki:TracAdmin trac-admin] will lock the database while copying. |
---|
17 | |
---|
18 | The resulting backup directory is safe to handle using standard file-based backup tools like `tar` or `dump`/`restore`. |
---|
19 | |
---|
20 | Please note, the `hotcopy` command will not overwrite a target directory and when such exists, the operation ends with an error: `Command failed: [Errno 17] File exists:` This is discussed in [trac:ticket:3198 #3198]. |

22 | === Restoring a Backup |
---|
23 | |
---|
24 | To restore an environment from a backup, stop the process running Trac, ie the Web server or [wiki:TracStandalone tracd], restore the contents of your backup (path/to/backupdir) to your [wiki:TracEnvironment project environment] directory and restart the service. |
---|
25 | |
---|
26 | To restore a PostgreSQL database backup, use the command: |
---|
27 | {{{#!sh |
---|
28 | psql -U <user> -d <database> -f postgresql.dump |
---|
29 | }}} |
---|
30 | The `<database>` option is the same as the [TracEnvironment#DatabaseConnectionStrings database connection string] in the `[trac]` `database` option of //trac.ini//. |
