I’ve done some testing and from what I’ve seen so far it looks really good.
What I’ve done is the following:
– having a test VPS with a few sites on it (1 user with magento, 1 user with wordpress, other, and admin) – 3 cpu cores
– the rsync script
– made .tar.gz backups to see how long it takes, and how much space it requires
– made .tar backups to see how long that takes, and how much space it requires
– rsyn’d the .tar files
– modified some files, database to get a different backup
– made .tar backups again
– use rsync again
This is the result:
– Creating .tar.gz files took about 3 minutes.
– Creating .tar files was under a minute, xx seconds
First time rsync:
sent 91 bytes received 83176231 bytes 3539417.96 bytes/sec
total size is 222105600 speedup is 2.67
Second time rsync:
sent 152532 bytes received 129556 bytes 26865.52 bytes/sec
total size is 221501440 speedup is 785.22
Though the .tar files take up more space, they’re way faster done. Because its not compressed, it can be rsynced and only changes will be transfered; saving time and bandwidth – yet you also have retention. Of course I tested this on a very small scale, but its supposed to work the same on larger numbers.
Is anyone using something similar like this, or has any thoughts on it?
