Backup format changed -
06-22-2008, 05:09 PM
This week we have switched the way backups are performed in order to speed the servers up.
Each night every site was archived in tar.gz (zipped) format, which adds some load to the server
Now we are copying the files directly over, with no compression. This reduces the time to create backups by about 90% because only files that changed since the last backup are moved, and even those are moved without causing a higher load on the cpu.
The main benefit is that all servers run with very low cpu loads, all the time.
We also added 2GB of off site backup storage to make up for the fact that sites are not stored in compressed format.
