I use rsnapshot (rsync/hardlink scripts) to back up my main server. |

Rsync can really be a memory hog. In this case it is the process of |
| 11 |
building a file list that consumes a lot of memory. |

You'll find that splitting up the sync job into several discrete |
| 14 |
directories (IE, back up /usr /home/ /etc seperately) works well to |
| 15 |
mitigate the huge memory usage. |
