|Backup.local||Good||No network load at all, unless using a network filesystem like NFS||Good||Very CPU intensive||Poor - no true incrementals||Poor - no true incremetals||Poor - all files are read||Very CPU intensive||Nice - from reblock|
|Backup.SRB||Good||Good||About one half to one third as disk bandwidth efficient as Backup.local, Backup.rsync or Backup.remote||Very CPU intensive||Poor - no true incrementals||Poor - no true incrementals||About one half to one third as disk bandwidth efficient as Backup.local, Backup.rsync or Backup.remote||Very CPU intensive||Nice - from reblock|
|Backup.rsync||About half as space efficient as Backup.local, Backup.SRB and Backup.remote||About half as network efficient as Backup.SRB and Backup.remote||Good||Very CPU efficient||Quite good - essentially all backups look like a fullsave, but only one copy of a given file is stored for a given host.||Very good - only new files and changed regions of modified files are transmitted||Quite good - only changed files are read||Very CPU efficient||So so - from rsync|
|Backup.remote||Good||Good||Good||Very CPU intensive||Poor - no true incrementals||Poor - no true incrementals||Poor - all files are read||Very CPU intensive||Nice - from reblock|
seki-strombrg> ~/public_html/Backup.local --help Usage: /Dcs/seki/strombrg/public_html/Backup.local [--normal|--overwrite|--help] Normal mode will do a backup with rotation Overwrite mode will overwrite the last daily backup, without doing any rotation at all. It's for redoing a backup when a previous one fails.
seki-strombrg> ~/bin/Backup.rsync --help Usage: /Dcs/seki/strombrg/bin/Backup.rsync --srcdir srcdir --dstdir dstdir --num-to-keep num-to-keep --use-compression --num-to-keep is the number of snapshots to keep
