Yes, we do use pretty much the setup you describe, i.e. rsync push to backup server, btrfs volume with daily snapshot subvolumes on the server. This particular setup has been in use for more than two years by now, and is working well with 8-10 servers (totals for all backed-up filesystems is about 1.2TiB/2.5M files of varying size; transferred daily delta is of course just a fraction of this). The backup server is a rather modest self-built Mini-ITX Core i5 with 8GiB RAM and 6TiB hardware (3ware) RAID-10 storage volume. Using btrfs volume in btrfs-raid configuration (raid-1 for data and metadata) would provide protection against data bit-rot. We use several such volumes on some of our severs, though not in combination with btrfs snapshot subvolumes. - -- Sarunas Burdulis http://math.dartmouth.edu/~sarunas -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJWJollAAoJEAcPjabqyGA9iD4H/2Hxa4IqYxRRLi55kg8c/tOS UafxgMMnUB498HHVGMldDZdjqmzBd4djHuVOeJPguu7RaSVKOIBBdpmZdI44LXoj y3P0m7Ig1cg3kGB7tZTgG6mzsgZQln6F8uW/lNox9EikmWUQ2eQZYIDVbLTEOLXt pMKVTKQeR1Jdl9HvbIqlPBpniqHn+JvesWUeTDdo47i45jcfRonYfPay0/ua7ql0 n80ObcOLlYSCw/rKZbkspHz7k9PMEEdeosbkvUkw2ZiGq13E1j6DFwSUTxcrMPhR Ffd+bL5c0CtKOTVrvtZdahJZ5U/Kl/QG1c78TsJagCN7YTSXRWnDSn6acdDRPmM= =Edp3 -----END PGP SIGNATURE-----
