Question Backup naming convention

[WhiteTiger]

Server operating system version

Ubuntu 24.04.2 LTS

Plesk version and microupdate number

18.0.69 #3

I can't figure out the convention used for Plesk backup, to find the backup of a given day.
I asked for a daily incremental backup, with a Weekly Full and rotation of 4 backups.

I also didn't understand if it's possible to configure the Full on a given day (with the Free version).

This is the list of the latest backups performed.

Hello, @WhiteTiger . Source:

a suffix designating the backup creation date is always added to each backup file, and the date format is <yymmddhhmm>. For example, the files of a backup created on 6 April 2011, 8:58 PM will have the suffix 1104062058

So, in your case 8th of May, 2025, 00:06 AM

Tanks, but I see two dates backup_2505080006_2505130006.tar
Is the second date the incremental one?

Also, can I configure the day to do the full?

Correct, 2505080006 is the timestamp of the full backup and 2505130006 of the incremental.

The full backups are those without an additional timestamp, for example backup_2505080006.tar.

Well, I understood how to identify the file.

But I also asked how to change the day of execution of the Full, for example Sunday evening and not Thursday as it is now.

By default when using incremental backups, the first full backup is made when you enable the backup schedule. So if you enabled incremental backups on a Thursday, a full backup will be made every Thursday.

There isn't an option (to my knowledge at least) to select a specific day for the full backup. However, if you want to have a full backup made every Sunday instead of Thursday, you'd have to logon to Plesk on a Saturday (assuming that you run your backups at AM time) and manually delete all incremental backups from the previous week. That will cause the backup manager to run a full backup the next time (which will be a Sunday) and start the incremental backup cycle again.

There is a caveat, because whenever a scheduled backup fails, the backup cycle moves to the next day.

Alternatively, purchasing the "Backup to Cloud Pro" extension will allow you to create a more flexible backup schedule. With the options to daily, weekly and monthly together (independent of each other). Meaning you can run daily incremental backups with a full backup every week and an additional weekly backup on a fixed day.
