solution for migrate large websites?
I have a few websites with a large number of files. Ever time I backup, I use tar+7z. tar the whole folder and 7z it into numbers of files. like the following
tar cf - folder | 7z a -si file.tar.7z -v256m
My folder is like 20G+ (will reach 30G soon) so the backup is a pain every time.
I have no problem with this backup way when I use KVM VPS. a few OpenVZ providers limit the I/O usage and CPU usage so the backup can't succeed but some OVZ are fine. (For slow I/O node, it's extremely likely to end up a fail.)
I'm used to the snapshot from DigitalOcean and at the moment trying the bandwagonhosting's new snapshot function for their OVZ.
I wonder beside the snapshot from some providers, if there is an alternative efficient way for large backup without upset the provider/node/neighbors.
