2. database logs

3. database backups

Naturally the backups must be stored separately from the logs and the databases, otherwise

the value of the backups reduces significantly. The databases and the related logs are

expected to be accessible easily from the hosting server but it is encouraged to use separate

physical file systems for these two.

NOTE: log files and databases residing in the same

physical disk mean duplicate disk operation efforts on the

same device. It is good design to separate logs and actual

databases to different physical storage devices.

Changing backup settings

Install time gives the option to set all the backup related settings.

To change the settings while the system is installed and in production later, please use the

tool 7db and the backup sub-command. Complete guide to 7db tool is in the appendix of

Deployment Guide.

Below there are example commands to give the reader an overview:

# 7db backup remove

# 7db backup set weekly Wed 00:30 /mnt/backups /mnt/backups

# 7db backup set daily 03:00 /mnt/backups

# 7db backup set directory /mnt/newbackups

# 7db backup set weekly Sun 01:30

# 7db backup set type online

# 7db backup now /mnt/backups online

Restoring backups

Backups are located in the user-defined directory. Backup files contain timestamp in the

name, also the operating system timestamp exists.

NOTE: the user must be aware which backup file should

be used. Therefore it is essential to understand the

backup system and the related files.

Based on this information one must choose which backup to restore.

Restore command is

# 7db backup restore <absolute-file-path>
