My version of "keep daily backups"

[WhiteDog]

As a host, I've always wanted to store multiple copies of my users backups. I also feel that the current daily / weekly : monthly system is outdated as all my users have databases which change so often that, restoring a monthly backup, would be setting them back to the stone age

There are a few scripts floating around which keep multiple versions of backups / copy the daily to the "day of the week". I was not 100% satisfied with those solutions, so I came up with my own solution. Some pointers on where my script differs from the others. Read below carefully!

• This script runs BEFORE cpbackup, so place it in /scripts/precpbackup
• No backups are copied, they are renamed. This saves on disk space and IO.
• You have to configure cPanel to ONLY tae a DAILY backup. The script will handle the weekly. As no weeklies are created, again saving on IO.
• You can define the number of daily / weekly copies to keep. Monthlies are not created as i don't need that.
• Because daily and weekly folders still exist, they can sttill be downloaded by the end-user from within cPanel.

How the script works:

• The script runs BEFORE the backups are taken.
• Your current "daily" is renamed to "daily_YYYYMMDD_HHMM" or "weekly_YYYYMMDD_HHMM". The date is the date that the folder was created (so generally yesteday date).
• weeklies / dailies are deleted if their number exceeds the value set (DAYS_TO_KEEP / WEEKS_TO_KEEP)

And finally, the script:

The only part I'm not yet 100% happy with is that sometimes your weekly is more newer then your daily. Not confusing to me but might be for the end-user downloading from within cPanel. I will probably change this someday into a system I like better.

As I can't seem to edit the starting post, here is an improved versin as cpbackup sometimes fzils to start if there is no "daily" present:

exactly what i was looking for thanks for sharing. how do you get this script to run before the backup?
