getFilesystemIteratorRules

protected Map<String,FilesystemIteratorRule> getFilesystemIteratorRules(FileReplication ffr)
                                                                 throws IOException,
SQLException

Description copied from class: FileEnvironment

Gets the default set of filesystem rules for this environment. This should not include file backup settings, they will override the values returned here. The returned map may be modified, to maintain internal consistency, return a copy of the map if needed.

Specified by:

getFilesystemIteratorRules in class FileEnvironment

Throws:

IOException

SQLException

getFilesystemIteratorPrefixRules

protected Map<String,FilesystemIteratorRule> getFilesystemIteratorPrefixRules(FileReplication ffr)
                                                                       throws IOException,

getModifyTime

public long getModifyTime(FileReplication ffr,
 String filename)
                   throws IOException

Because some of the backup servers use ext2/ext3 filesystems, which have only one-second time accuracy, timestamps are rounded down to the nearest second. (Truncates the milliseconds component) When all servers support more granular file timestamps, or if we store the more accurate timestamps in extended attributes, then we can remove this for potentially greater accuracy in detecting file changes.

Specified by:

getModifyTime in interface BackupEnvironment

Overrides:

getModifyTime in class FileEnvironment

Throws:

IOException
