# Backup and restore
|
|
|
|
## Backup
|
|
|
|
To back up a WeeWX installation, you will need to make a copy of
|
|
|
|
* the configuration information (`weewx.conf`),
|
|
* skins and templates,
|
|
* custom code, and
|
|
* the WeeWX database.
|
|
|
|
The location of these items depends on how you installed WeeWX.
|
|
|
|
=== "Debian"
|
|
|
|
| Item | Location |
|
|
|---------------|----------------------------|
|
|
| Configuration | `/etc/weewx/weewx.conf` |
|
|
| Skins | `/etc/weewx/skins` |
|
|
| Custom code | `/usr/share/weewx/user` |
|
|
| Database | `/var/lib/weewx/weewx.sdb` |
|
|
|
|
=== "Redhat"
|
|
|
|
| Item | Location |
|
|
|---------------|----------------------------|
|
|
| Configuration | `/etc/weewx/weewx.conf` |
|
|
| Skins | `/etc/weewx/skins` |
|
|
| Custom code | `/usr/share/weewx/user` |
|
|
| Database | `/var/lib/weewx/weewx.sdb` |
|
|
|
|
=== "openSUSE"
|
|
|
|
| Item | Location |
|
|
|---------------|----------------------------|
|
|
| Configuration | `/etc/weewx/weewx.conf` |
|
|
| Skins | `/etc/weewx/skins` |
|
|
| Custom code | `/usr/share/weewx/user` |
|
|
| Database | `/var/lib/weewx/weewx.sdb` |
|
|
|
|
=== "pip"
|
|
|
|
| Item | Location |
|
|
|---------------|-----------------------------------|
|
|
| Configuration | `~/weewx-data/weewx.conf` |
|
|
| Skins | `~/weewx-data/skins` |
|
|
| Custom code | `~/weewx-data/user` |
|
|
| Database | `~/weewx-data/archive/weewx.sdb` |
|
|
|
|
It is not necessary to back up the generated images, HTML files, or NOAA
|
|
reports, because WeeWX can easily regenerate them.
|
|
|
|
It is also not necessary to back up the WeeWX code, because it can be
|
|
installed again. However, it doesn't hurt to do so.
|
|
|
|
!!! Note
|
|
For a SQLite configuration, do not make the copy of the database file
|
|
while in the middle of a transaction! Schedule the backup for immediately
|
|
after an archive record is written, and then make sure the backup
|
|
completes before the next archive record arrives. Alternatively, stop
|
|
WeeWX, perform the backup, then start WeeWX.
|
|
|
|
!!! Note
|
|
For a MySQL/MariaDB configuration, save a dump of the archive database.
|
|
|
|
## Restore
|
|
|
|
To restore from backup, do a fresh installation of WeeWX, replace the
|
|
configuration file, skins, and database with those from a backup, then start
|
|
`weewxd`.
