Class LinuxServerEnvironment

com.aoindustries.aoserv.backup.FileEnvironment

com.aoindustries.aoserv.backup.PosixFileEnvironment

com.aoindustries.aoserv.daemon.backup.LinuxServerEnvironment

All Implemented Interfaces:

BackupEnvironment

public class LinuxServerEnvironment
extends PosixFileEnvironment

An LinuxServerEnvironment controls the backup system on an Server.

TODO: Save bandwidth by doing prelink -u --undo-output=(tmpfile) (do this to read the file instead of direct I/O). Can possibly use the distro data to know which ones are prelinked.

TODO: Use LVM snapshots when is a domU - also do MySQL lock to get steady-state snapshot

TODO: Should we use some tricky stuff to dump the databases straight out as we iterate? (Backups only) TODO: Or, just dump to disk and remove when completed? (Backups only)

TODO: Adhere to the d attribute? man chattr
