Personally I prefer FreeBSD's approach beacuse, when doing this type of things, we are potentially breaking semantics of the original utility and hence may make errors on ther systems. A possible solution might be have a cron script that periodically takes snapshot of the file system (for example, one per one hour). While snapshot alone could be considered to be a complete backup solution, it is possible to save our time when recovering files from earlier snapshots, and it will be even possible to retrieve earlier versions of files. However, the overhead when taking the snapshots is not so neglectable (for a large file system, it will take several seconds for a snapshot to be taken). This approach is more similiar with Windows's recycle bin approach, but does not help in the download-and-rm case if there's no snapshot taken between download and rm. --=20 Xin LI <delphij frontfree net> http://www.delphij.net/ See complete headers for GPG key and other information. --Q68bSM7Ycu6FN28Q Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAhT0cOfuToMruuMARAnwZAJ9mMwjMf3ooAjTLW/loPhfTTNsEdgCfbUC7 XdiKLpG8r2TgId1V/qesOd4= =nsj8 -----END PGP SIGNATURE----- --Q68bSM7Ycu6FN28Q--
