NAME
ubBackup – backup Unibase applications and user data
SYNOPSIS
ubBackup {–app <application>} {–customer <customer>} {–days <days of backups to retain (default 14)>} {–extra <extra directories to backup>} {–remote <remote rsync offsite>} {–verbose}
DESCRIPTION
ubBackup is used to backup Unibase applications and should be used daily.
To set up a daily backup put ubBackup as a command in /etc/cron.daily. The simplest way to do this is symbolically link it to the directory.
For more complex cases, eg limiting the number of backup days, it is recommended to create a small bash script in /usr/local/app and symbolically link that to /etc/cron.daily.
ubBackup backs up into the directory /ubBackup. If this directory doesn’t exist ubBackup will create. WARNING: backups can get big over time. It is recommended that /ubBackup be created manually as a symbolic link to a large enough backup device. The permissions should be drwx—— and it should be owned by root.
The directory structure below /ubBackup is:
_APPS – backups of application source code
<customers> – backups of customer data. This is stored as .Agz, .num, and .seq files produced by ubTableDump. Directories in /data/<customer>/<application> are backed up as tar.gz files, except for tmp which is cleared.
app – /usr/local/app/*.[dk]* backed up as <date>.tar.gz
extra – extra backups from –extra flag
In each of these directories a directory for the backup date is created to hold the backup. eg a backup date 1 December 1970 would have the date 19701201 and application source would be stored in /ubBackup/_APPS/19701201/
FLAGS
| –app | Specify application to backup. Default is all applications |
| –customer | Specify customer to backup. Default is all customers. Note this might overwrite an existing backup. |
| –days | Number of days of backups to retain. Default is 14 |
| –extra | Extra customer directories to backup. This is a comma separated list. Each directory is specified in two parts: <full path name>:<tar name> eg /home:HOME,root:ROOT The extra directories are backed up to /ubBackup/extra/<date> |
| –remote | rsync remote user and location for offsite backup. eg ec2-user@<backup server>:/backup |
| –verbose | ubBackup normally works silently. If you want to see the progress of ubBackup use –verbose. Either way the backup progress is logged in the system log (/var/log/messages or journalctl) |
