Hello to everyone,
Lately for some reason, BackupPC has been running very slow on a server that
we have configured to do backups. Just so that you guys can have an idea of
how slow it really is going, it took BackupPC 10265.2 minutes to backup
1656103 files totaling to only 24 gigabytes worth of files. Obviously, I
can't really wait a week for a 24 gigbyte backup to be done. Now here's what
makes me think that this problem with BackupPC could be due to server
hardware: I first started started doing backups for one pc at a time, and it
took BackupPC 468.8 minutes to backup 2626069 files or 32 gigabyte worth of
files for that same computer. But now I have about 45 computers added to
BackupPC and sometimes BackupPC is backing up 30 of them or more at the same
time, and that's when the server really goes slow.
Here's the top command when the BackupPC server is going slow:
top - 19:06:36 up 15 days, 6:11, 3 users, load average: 28.76, 39.03,
32.14
Tasks: 156 total, 1 running, 155 sleeping, 0 stopped, 0 zombie
Cpu(s): 3.7% us, 2.2% sy, 0.0% ni, 7.7% id, 86.0% wa, 0.4% hi, 0.0% si
Mem: 1033496k total, 1019896k used, 13600k free, 141720k buffers
Swap: 5116692k total, 2538712k used, 2577980k free, 41932k cached
Here's the hardware and BackupPC specs: BackupPC is running on server that
has 5 terabytes of disk space, 1 gb of RAM, and a 5 gb swap, with intell
xeon processor. I was using rsync as my backup method, but I switched to tar
to see if that would improve performance. BackupPC is backing up about 45
servers (all linux).
So in conclusion, how can I make BackupPC run faster? What's the fastest
backup method, what can I modify on config.pl to make it run faster, etc? Is
not enough RAM what's causing backuppc to run slow? Is there anything on my
hardware that would make it run faster?
Thank you, and I hope that you guys can help me with speeding up BackupPC!
