Re: [BackupPC-users] Backing up a BackupPc host
2009-03-10 12:46:38
I checked the cpool directory on my server and it contained 803,023
files in the directory tree. If rsync is not a scaleable solution for
backing up a backuppc pool over the internet, does anyone have a
suggestion for a better solution?

The problem with rsync'ing a backuppc data pool is the sheer number of
files. you'll run your machine out of space with the lists as they get
loaded into memory.
up to a certain point it will work; and with newer versions of rsync it will
work better; but it is not a scaleable solution.
More specifically it is the number of hardlinks that most file-oriented
copying methods have to track by keeping tables of inode numbers in
memory and matching them up - and the fact that to work, the entire tree
containing pool/cpool/pc directories must be processed at once.
