Is BZip2 compression supported? Which compression methods are supported?

SyncBackPro supports BZip2 compression, as well as Deflate, Deflate64, BWT and LZMA. It also supports the encryption method used by SecureZip to encrypt the filenames in the Zip file.

SyncBackSE supports
Deflate, Deflate64, and BWT. It also supports the encryption method used by SecureZip to encrypt the filenames in the Zip file.

SyncBackLite/Free supports only Deflate compression.

Files compressed with Deflate can be opened by practically any type of compression utility. The disadvantage is that it is least efficient compression method.

Deflate64 is an enhanced version of Deflate, and can be opened by most compression utilities.

BZip2 is an advanced compression method that is support by some compression utilities, e.g. WinZip 10 or newer and 7Zip.

BWT compressed files can only be opened with SyncBackSE or SyncBackPro.

LZMA uses an improved and optimized version of the Lempel-Ziv (LZ77) compression algorithm, backed by a Markov chain range encoder. It uses a variable dictionary size. It is compatible with some compression programs, e.g. WinZip 12. LZMA typically provides much better compression than the Deflate and Deflate64 algorithms at the expense of speed and memory usage when compressing. It also typically provides compression ratios a little better than BZip2/BWT while being a little faster.

If filename encryption is used then the compressed files can be opened with SyncBackPro, SyncBackSE and SecureZip (by PKWare).
